The accompanying drawing explanation
Fig. 1 is that structure of the present invention forms schematic diagram.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1: a kind of indoor distributed system MIMO antenna, comprise a base 1, this base 1 adopts plane sheet reflector, is used to form the directed radiation of signal.One
perpendicular polarization unit2 and a
horizontal polarization unit3 are installed on base 1, described
perpendicular polarization unit2 and one, 3 interval, horizontal polarization unit distance; Described
perpendicular polarization unit2 is connected with the
first feeder line41, and described
horizontal polarization unit3 is connected with the second feeder line 42.Two radiating elements installing on base 1, the polarised direction difference, be conducive to realize higher Signal segregation degree like this.
Particularly, described
perpendicular polarization unit2 comprises the
first sheet metal21 and the
second sheet metal22; Described the
second sheet metal22 vertically arranges, and an end of the
second sheet metal22 is fixed on base 1, and the other end is to a side horizontal buckling; One end of described the
first sheet metal21 is connected by rivet with that end of the
second sheet metal22 horizontal bucklings, and the other end is fixed on the
first support5, and described the
first support5 vertically is fixed on base 1.The
first support5 needs to adopt insulating material, can be plastics.
Preferably, the
second sheet metal22 is 3 settings towards the horizontal polarization unit, and the
second sheet metal22 just can play certain signal buffer action.
Particularly, described
horizontal polarization unit3 comprises a printed circuit board (PCB), has the circuit for emission level polarised direction signal on this printed circuit board (PCB).Described printed circuit board (PCB) is T-shaped.
Due to a hemispheric outer cover (not drawing in Fig. 1) can also be installed on base 1 usually, for the form fit with outer cover, printed circuit board (PCB) is lean-in tiltedly to be arranged on base 1.
Have a plurality of holes on described base 1, the
first feeder line41 is connected with described
perpendicular polarization unit2 through the Kong Houzai on base 1, and the
second feeder line42 is connected with described
horizontal polarization unit3 through the Kong Houzai on base 1; Described the

second feeder line42 are fixed on base 1 by
stator6.
6 is conductive metal sheets, plays the ground connection effect when playing fixation.For this reason, the
first feeder line41 and the
second feeder line42 are removed with the insulating outer layer of
stator6 contacts site, expose the ground plane under insulating outer layer,
stator6 just naturally contact with the ground plane of feeder line when fixing feeder line, thereby makes the
first feeder line41 and the
second feeder line42 and base 1 formation grounding connection.And the heart yearn of the
first feeder line41 is connected with the
