Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
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 unit 2 and a horizontal polarization unit 3 are installed on base 1, described perpendicular polarization unit 2 and one, 3 interval, horizontal polarization unit distance; Described perpendicular polarization unit 2 is connected with the first feeder line 41, and described horizontal polarization unit 3 is connected with the second feeder line 42.Two radiating elements installing on base 1, polarised direction is different, is conducive to like this realize higher Signal segregation degree.
Particularly, described perpendicular polarization unit 2 comprises the first sheet metal 21 and the second sheet metal 22; Described the second sheet metal 22 vertically arranges, and one end of the second sheet metal 22 is fixed on base 1, and the other end is to a side horizontal buckling; One end of described the first sheet metal 21 is connected by rivet with that end of the second sheet metal 22 horizontal bucklings, and the other end is fixed on the first support 5, and described the first support 5 is vertically fixed on base 1.The first support 5 need to adopt insulating material, can be plastics.
Preferably, the second sheet metal 22 is 3 settings towards horizontal polarization unit, and the second sheet metal 22 just can play certain signal buffer action.
Particularly, described horizontal polarization unit 3 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 conventionally, for the form fit with outer cover, printed circuit board (PCB) is lean-in to be tiltedly arranged on base 1.
