In addition, in the prior art, the ground metal sheet is used to adjust the equivalent ground plane length of the antenna element, so that the operating bandwidth of the antenna element in a specific frequency band can be increased. However, this method of additionally arranging the ground metal sheet will consume more hardware space, thereby limiting the development of the handheld device in terms of thinner and lighter.

具体实施方式detailed description
图1为本发明一实施例的手持式装置的示意图。如图1所示，手持式装置100包括接地面110、第一天线元件120与第二天线元件130。其中，接地面110包括短边111、第一长边112与第二长边113。此外，短边111与第一长边112彼此相邻并相交，且短边111与第一长边112的相交处形成第一转角101。相似地，短边111与第二长边113彼此相邻并相交，且短边111与第二长边113的相交处形成第二转角102。FIG. 1 is a schematic diagram of a handheld device according to an embodiment of the present invention. As shown in FIG. 1 , the handheld device 100 includes a ground plane 110 , a first antenna element 120 and a second antenna element 130 . Wherein, the ground plane 110 includes a short side 111 , a first long side 112 and a second long side 113 . In addition, the short side 111 and the first long side 112 are adjacent to and intersect each other, and the intersection of the short side 111 and the first long side 112 forms the first corner 101 . Similarly, the short side 111 and the second long side 113 are adjacent to and intersect each other, and the intersection of the short side 111 and the second long side 113 forms the second corner 102 .
在配置上，接地面110、第一天线元件120与第二天线元件130位于同一水平面。例如，在一实施例中，手持式装置100还包括一基板(未示出)，且接地面110、第一天线元件120与第二天线元件130皆配置在所述基板的一表面上。此外，第一天线元件120相对于短边111，且第二天线元件130相对于第一长边112。也即，第一天线元件120是沿着接地面110的短边111配置，且第二天线元件130是沿着接地面110的第一长边112配置。In configuration, the ground plane 110 , the first antenna element 120 and the second antenna element 130 are located on the same horizontal plane. For example, in one embodiment, the handheld device 100 further includes a substrate (not shown), and the ground plane 110 , the first antenna element 120 and the second antenna element 130 are all disposed on a surface of the substrate. In addition, the first antenna element 120 is opposite to the short side 111 , and the second antenna element 130 is opposite to the first long side 112 . That is, the first antenna element 120 is disposed along the short side 111 of the ground plane 110 , and the second antenna element 130 is disposed along the first long side 112 of the ground plane 110 .
更进一步来看，第一天线元件120为一单极天线(monopole antenna)。此外，第一天线元件120电性连接至信号源S11，并邻近接地面110的第二转角102。第二天线元件130包括第一辐射部131与馈入部132。其中，第一辐射部131的一端电性连接第一长边112并邻近第一转角101。换言之，第二天线元件130具有一接地端，且第二天线元件130的接地端邻近接地面110的第一转角101。再者，第一辐射部131通过馈入部132电性连接至信号源S12。藉此，第二天线元件130将可形成一平面倒F形天线(planar inverted-F antenna)。Further, the first antenna element 120 is a monopole antenna. In addition, the first antenna element 120 is electrically connected to the signal source S11 and is adjacent to the second corner 102 of the ground plane 110 . The second antenna element 130 includes a first radiating portion 131 and a feeding portion 132 . Wherein, one end of the first radiation portion 131 is electrically connected to the first long side 112 and is adjacent to the first corner 101 . In other words, the second antenna element 130 has a ground terminal, and the ground terminal of the second antenna element 130 is adjacent to the first corner 101 of the ground plane 110 . Furthermore, the first radiating part 131 is electrically connected to the signal source S12 through the feeding part 132 . Accordingly, the second antenna element 130 can form a planar inverted-F antenna.
在操作上，信号源S11可提供馈入信号给第一天线元件120。藉此，第一天线元件120将可产生激发模态，并操作在第一频带下。此外，手持式装置100可通过第二天线元件130来调整第一天线元件120的等效接地面长度。藉此，将可提升第一天线元件120的特性，并有助于手持式装置100在轻薄化上的发展。In operation, the signal source S11 can provide a feed signal to the first antenna element 120 . Accordingly, the first antenna element 120 can generate excitation modes and operate in the first frequency band. In addition, the handheld device 100 can adjust the equivalent ground plane length of the first antenna element 120 through the second antenna element 130 . In this way, the characteristics of the first antenna element 120 can be improved, and contribute to the development of thinner and lighter handheld device 100 .
举例来说，当第一天线元件120进行操作时，手持式装置100可关闭信号源S12，以致使第二天线元件130停止操作(也即，停止收发电磁波)。此外，随着第一天线元件120的操作，接地面110上将分布着第一天线元件120的激发电流。此外，接地面110上的激发电流主要集中在接地面110的第一转角101与第二转角102。换言之，第二天线元件130的接地端邻近第一天线元件120的激发电流的最强处。藉此，手持式装置100可通过第二天线元件130来调整第一天线元件120的等效接地面长度。For example, when the first antenna element 120 is operating, the handheld device 100 can turn off the signal source S12, so that the second antenna element 130 stops operating (ie, stops transmitting and receiving electromagnetic waves). In addition, with the operation of the first antenna element 120 , the excitation current of the first antenna element 120 will be distributed on the ground plane 110 . In addition, the excitation current on the ground plane 110 is mainly concentrated on the first corner 101 and the second corner 102 of the ground plane 110 . In other words, the ground terminal of the second antenna element 130 is adjacent to the strongest excitation current of the first antenna element 120 . Thereby, the handheld device 100 can adjust the equivalent ground plane length of the first antenna element 120 through the second antenna element 130 .
在图1实施例中，第一辐射部131与短边111的长度总和可用以界定第一天线元件120的等效接地面长度。也即，倘若短边111的长度为长度L11，且第一辐射部131的长度为长度L12时，则第一天线元件120的等效接地面长度相当于长度L11与长度L12的相加。此外，第一天线元件120的等效接地面长度可例如是第一天线元件120的中心频率的0.44～0.46倍波长。换言之，在一实施例中，第一辐射部131与短边111的长度总和(也即，长度L11与长度L12的相加)可例如是第一天线元件120的中心频率的0.44～0.46倍波长。In the embodiment of FIG. 1 , the sum of the lengths of the first radiating portion 131 and the short side 111 can be used to define the equivalent ground plane length of the first antenna element 120 . That is, if the length of the short side 111 is the length L11 and the length of the first radiation portion 131 is the length L12, the equivalent ground plane length of the first antenna element 120 is equal to the sum of the length L11 and the length L12. In addition, the equivalent ground plane length of the first antenna element 120 may be, for example, 0.44˜0.46 times the wavelength of the center frequency of the first antenna element 120 . In other words, in one embodiment, the sum of the lengths of the first radiating portion 131 and the short side 111 (that is, the sum of the length L11 and the length L12) may be, for example, 0.44˜0.46 times the wavelength of the center frequency of the first antenna element 120 .
具体而言，在图1实施例中，接地面110对第一天线元件120来说不具有最佳的尺寸，因此本实施例在适当的位置设置第二天线元件130。藉此，第二天线元件130除了可以用以收发电磁波以外，还可以将第一天线元件120在短边111上的等效接地面长度调整至最佳值，进而提升第一天线元件120的特性(例如，操作带宽)。Specifically, in the embodiment of FIG. 1 , the ground plane 110 does not have an optimal size for the first antenna element 120 , so in this embodiment, the second antenna element 130 is disposed at a proper position. In this way, in addition to being able to transmit and receive electromagnetic waves, the second antenna element 130 can also adjust the equivalent ground plane length of the first antenna element 120 on the short side 111 to an optimal value, thereby improving the characteristics of the first antenna element 120 (eg, operating bandwidth).
举例来说，图2为本发明一实施例的第一天线元件的返回损失(return loss)示意图，图3为本发明一实施例的第二天线元件的返回损失示意图，且图4为本发明一实施例的第一天线元件的天线效率示意图。在图2-4实施例中，接地面110的尺寸约为180x100mm2，第一天线元件120的尺寸约为67x5mm2，且第二天线元件130的尺寸约为53x10mm2。For example, FIG. 2 is a schematic diagram of the return loss (return loss) of the first antenna element according to an embodiment of the present invention, FIG. 3 is a schematic diagram of the return loss of the second antenna element according to an embodiment of the present invention, and FIG. 4 is a schematic diagram of the return loss of the second antenna element according to the present invention. A schematic diagram of the antenna efficiency of the first antenna element of an embodiment. In the embodiment of FIGS. 2-4 , the ground plane 110 has a size of about 180x100mm 2 , the first antenna element 120 has a size of about 67x5mm 2 , and the second antenna element 130 has a size of about 53x10mm 2 .
如图2所示，返回损失曲线210用以表示在未设置第二天线元件130下的返回损失，且返回损失曲线220用以表示在设置第二天线元件130下的返回损失。就返回损失曲线210与返回损失曲线220来看，在未设置第二天线元件130下，第一天线元件120操作在900MHz附近时的阻抗匹配不佳，而当第二天线元件130被设置时，第一天线元件120将可涵盖822MHz～964MHz。换言之，第二天线元件130可有效地提升第一天线元件120的操作带宽，以致使可涵盖GSM850/900频带。As shown in FIG. 2 , the return loss curve 210 is used to represent the return loss without the second antenna element 130 , and the return loss curve 220 is used to represent the return loss with the second antenna element 130 installed. As far as the return loss curve 210 and the return loss curve 220 are concerned, when the second antenna element 130 is not provided, the impedance matching of the first antenna element 120 is not good when it operates near 900MHz, and when the second antenna element 130 is provided, The first antenna element 120 will cover 822MHz~964MHz. In other words, the second antenna element 130 can effectively increase the operating bandwidth of the first antenna element 120 so as to cover the GSM850/900 frequency band.
再者，第二天线元件130也可用以收发电磁波。举例来说，如图3所示，第二天线元件130可例如是在操作在1,575MHz左右，以涵盖GPS频带。值得注意的是，第二天线元件130在操作下将不会针对第一天线元件120的特性进行改善。此外，当第二天线元件130停止操作时，第一天线元件120将可利用第二天线元件130将其等效接地面长度调整至最佳值，以藉此提升收发品质。举例来说，如图4所示，第一天线元件120操作在824MHz～960MHz时的天线效率约为57%～88%，进而满足手持式装置100在应用上的需求。Moreover, the second antenna element 130 can also be used to send and receive electromagnetic waves. For example, as shown in FIG. 3 , the second antenna element 130 may, for example, operate at around 1,575 MHz to cover the GPS frequency band. It should be noted that the second antenna element 130 will not improve the characteristics of the first antenna element 120 under operation. In addition, when the second antenna element 130 stops operating, the first antenna element 120 can use the second antenna element 130 to adjust its equivalent ground plane length to an optimal value, thereby improving the quality of transmission and reception. For example, as shown in FIG. 4 , the antenna efficiency of the first antenna element 120 is about 57%-88% when operating at 824MHz-960MHz, thereby satisfying the application requirements of the handheld device 100 .
虽然图1实施例列举了第一天线元件120与第二天线元件130的实施形态，但其并非用以限定本发明。举例来说，第一天线元件120也可是平面倒F形天线、环形天线(loopantenna)、偶极天线(dipole antenna)、槽孔天线(slot antenna)或是任何形态的天线。此外，第二天线元件130可例如是具有接地端的天线。Although the embodiment in FIG. 1 lists the implementation forms of the first antenna element 120 and the second antenna element 130 , it is not intended to limit the present invention. For example, the first antenna element 120 can also be a planar inverted-F antenna, a loop antenna, a dipole antenna, a slot antenna or any antenna. In addition, the second antenna element 130 may be, for example, an antenna with a ground terminal.
举例来说，图5为本发明另一实施例的手持式装置的示意图。图5所列举的手持式装置500基本上与图1所列举的手持式装置100相似。与图1主要不同之处在于，图5中的第二天线元件530是由第一辐射部531所构成。For example, FIG. 5 is a schematic diagram of a handheld device according to another embodiment of the present invention. The handheld device 500 shown in FIG. 5 is basically similar to the handheld device 100 shown in FIG. 1 . The main difference from FIG. 1 is that the second antenna element 530 in FIG. 5 is composed of the first radiation portion 531 .
具体而言，第一辐射部531的一端电性连接第一长边112并邻近第一转角101，且第一辐射部531的另一端电性连接至信号源S12。藉此，第二天线元件530将可形成一环形天线。此外，第一辐射部531与短边111的长度总和可用以界定第一天线元件120的等效接地面长度。也即，倘若第一辐射部531的长度为长度L52，则第一天线元件120的等效接地面长度相当于长度L11与长度L52的相加。Specifically, one end of the first radiation portion 531 is electrically connected to the first long side 112 and adjacent to the first corner 101 , and the other end of the first radiation portion 531 is electrically connected to the signal source S12 . In this way, the second antenna element 530 can form a loop antenna. In addition, the sum of the lengths of the first radiating portion 531 and the short side 111 can be used to define the equivalent ground plane length of the first antenna element 120 . That is, if the length of the first radiation portion 531 is the length L52, the equivalent ground plane length of the first antenna element 120 is equivalent to the sum of the length L11 and the length L52.
再者，与图1实施例相似地，当第一天线元件120进行操作时，第二天线元件530可停止操作(也即，停止收发电磁波)。此时，手持式装置500将可通过第二天线元件530来调整第一天线元件120的等效接地面长度，进而提升第一天线元件120的特性。再者，第二天线元件530也可进行收发电磁波的操作，且此时的第二天线元件530将不会针对第一天线元件120的特性进行改善。至于图5中各个元件的细部说明已包含在上述各个实施中，故在此不予赘述。Moreover, similar to the embodiment in FIG. 1 , when the first antenna element 120 is operating, the second antenna element 530 may stop operating (that is, stop transmitting and receiving electromagnetic waves). At this time, the handheld device 500 can adjust the equivalent ground plane length of the first antenna element 120 through the second antenna element 530 , thereby improving the characteristics of the first antenna element 120 . Furthermore, the second antenna element 530 can also perform the operation of transmitting and receiving electromagnetic waves, and at this time the second antenna element 530 will not improve the characteristics of the first antenna element 120 . The detailed description of each element in FIG. 5 has been included in the above implementations, so it will not be repeated here.
图6为本发明又一实施例的手持式装置的示意图。图6所列举的手持式装置600基本上与图1所列举的手持式装置100相似。与图1主要不同之处在于，图6的手持式装置600还包括第三天线元件610。FIG. 6 is a schematic diagram of a handheld device according to another embodiment of the present invention. The handheld device 600 shown in FIG. 6 is substantially similar to the handheld device 100 shown in FIG. 1 . The main difference from FIG. 1 is that the handheld device 600 in FIG. 6 further includes a third antenna element 610 .
具体而言，第三天线元件610相对于第二长边113。也即，第三天线元件610是沿着接地面110的第二长边113配置。此外，第三天线元件610包括第二辐射部611与馈入部612。其中，第二辐射部611的一端电性连接第二长边113并邻近第二转角102。换言之，第三天线元件610具有一接地端，且第三天线元件610的接地端邻近接地面110的第二转角102。再者，第二辐射部611通过馈入部612电性连接至信号源S61。藉此，第三天线元件610将可形成一平面倒F形天线。Specifically, the third antenna element 610 is opposite to the second long side 113 . That is, the third antenna element 610 is disposed along the second long side 113 of the ground plane 110 . In addition, the third antenna element 610 includes a second radiating portion 611 and a feeding portion 612 . Wherein, one end of the second radiation portion 611 is electrically connected to the second long side 113 and is adjacent to the second corner 102 . In other words, the third antenna element 610 has a ground terminal, and the ground terminal of the third antenna element 610 is adjacent to the second corner 102 of the ground plane 110 . Furthermore, the second radiation part 611 is electrically connected to the signal source S61 through the feeding part 612 . Accordingly, the third antenna element 610 can form a planar inverted-F antenna.
在操作上，当第一天线元件120进行操作时，手持式装置600可关闭信号源S12与信号源S61，以致使第二天线元件130与第三天线元件610停止操作(也即，停止收发电磁波)。此外，第二天线元件130与第三天线元件610的接地端皆邻近第一天线元件120的激发电流的最强处。因此，手持式装置600可通过第二天线元件130与第三天线元件610来调整第一天线元件120的等效接地面长度。藉此，将可提升第一天线元件120的特性，并有助于手持式装置600在轻薄化上的发展。In operation, when the first antenna element 120 is operating, the handheld device 600 can turn off the signal source S12 and the signal source S61, so that the second antenna element 130 and the third antenna element 610 stop operating (that is, stop transmitting and receiving electromagnetic waves ). In addition, the ground terminals of the second antenna element 130 and the third antenna element 610 are adjacent to the strongest excitation current of the first antenna element 120 . Therefore, the handheld device 600 can adjust the equivalent ground plane length of the first antenna element 120 through the second antenna element 130 and the third antenna element 610 . Thereby, the characteristics of the first antenna element 120 can be improved, and the development of the handheld device 600 in thinner and lighter will be facilitated.
在图6实施例中，第一辐射部131、第二辐射部611与短边111的长度总和可用以界定第一天线元件120的等效接地面长度。也即，倘若第二辐射部611的长度为L61，则第一天线元件120的等效接地面长度相当于长度L11、长度L12与长度L61的相加。此外，第一天线元件120的等效接地面长度可例如是第一天线元件120的中心频率的0.44～0.46倍波长。In the embodiment of FIG. 6 , the sum of the lengths of the first radiating portion 131 , the second radiating portion 611 and the short side 111 can be used to define the equivalent ground plane length of the first antenna element 120 . That is, if the length of the second radiation portion 611 is L61, the equivalent ground plane length of the first antenna element 120 is equivalent to the sum of the length L11, the length L12 and the length L61. In addition, the equivalent ground plane length of the first antenna element 120 may be, for example, 0.44˜0.46 times the wavelength of the center frequency of the first antenna element 120 .
换言之，在一实施例中，第一辐射部131、第二辐射部611与短边111的长度总和可例如是第一天线元件120的中心频率的0.44～0.46倍波长。再者，第二天线元件130与第三天线元件610也可分别用以收发电磁波，且此时的第二天线元件130与第三天线元件610将不会针对第一天线元件120的特性进行改善。此外，与图5实施例相似地，第三天线元件610也可直接由第一辐射部所构成，并将第一辐射部的另一端电性直接连接至信号源S61，以致使第三天线元件610形成一环形天线。至于图6中各个元件的细部说明已包含在上述各个实施中，故在此不予赘述。In other words, in one embodiment, the sum of the lengths of the first radiating portion 131 , the second radiating portion 611 and the short side 111 may be, for example, 0.44˜0.46 times the wavelength of the center frequency of the first antenna element 120 . Moreover, the second antenna element 130 and the third antenna element 610 can also be used to send and receive electromagnetic waves respectively, and at this time the second antenna element 130 and the third antenna element 610 will not improve the characteristics of the first antenna element 120 . In addition, similar to the embodiment in FIG. 5 , the third antenna element 610 can also be directly formed by the first radiating part, and the other end of the first radiating part is electrically connected directly to the signal source S61, so that the third antenna element 610 forms a loop antenna. The detailed description of each element in FIG. 6 has been included in the above implementations, so it will not be repeated here.
综上所述，本发明的手持式装置包括沿着接地面的短边与第一长边所设置的第一天线元件与第二天线元件，且第二天线元件的接地端邻近短边与第一长边相交而成的第一转角。藉此，第二天线元件除了可以用以收发电磁波以外，还可用以调整第一天线元件的等效接地面长度，进而提升第一天线元件的特性(例如，操作带宽)。换言之，本发明无须额外设置接地金属片就可提升第一天线元件的特性，因此有助于手持式装置在轻薄化上的发展。In summary, the handheld device of the present invention includes a first antenna element and a second antenna element disposed along the short side and the first long side of the ground plane, and the ground end of the second antenna element is adjacent to the short side and the first long side. The first corner where one long side meets the other. In this way, the second antenna element can not only be used for transmitting and receiving electromagnetic waves, but also can be used to adjust the equivalent ground plane length of the first antenna element, thereby improving the characteristics (eg, operating bandwidth) of the first antenna element. In other words, the present invention can improve the characteristics of the first antenna element without additionally disposing the ground metal sheet, thus contributing to the development of thinner and lighter handheld devices.
