Fig. 2 is the stereogram of another angle of the active antenna shown in Fig. 1;
The internal structure schematic diagram that Fig. 3 is the active antenna described in Fig. 1.
[embodiment]
Be further described the utility model below in conjunction with accompanying drawing and exemplary embodiment, wherein identical in accompanying drawing label all refers to identical parts.In addition, if the detailed description of known technology is for illustrating that feature of the present utility model is unnecessary, then omitted.
Fig. 1 to Fig. 3 collectively illustrates active antenna 100 of the present utility model, it comprises cabinet 10, is all built in the antenna assembly 20 of described cabinet 10, for the control device 30 of control antenna device 20 operating state and to be connected with described control device 30 and for realizing the external interface 8 that this active antenna 100 is connected with external equipment (not shown).
Described cabinet 10 comprises front panel 1, is divided into the side plate 3 of front panel 1 left and right sides for a pair, the top cover 2 being located at front panel about 1 two ends respectively and bottom 4, and relative with described front panel 1 and all with this metal bearing plate 5 that side plate 3, top cover 2 and bottom 4 are connected.
Described antenna assembly 20 comprises reflecting plate 15 and is fixedly arranged on several antenna oscillators 9 in described reflecting plate 15 one side.The another side of described reflecting plate 15 arranges described control device 30 and external interface 8, and described control device 30 is connected by radio frequency connecting piece (scheme not show, described radio frequency connecting piece can be radio frequency cable or radio frequency connector) with antenna oscillator 9.Described reflecting plate 15 fixes with described metal bearing plate 5, and wherein, one of antenna oscillator 9 place is installed facing to described front panel 1.
The power supply that described control device 30 comprises the central control unit for controlling each antenna oscillator operating state and powers for described central control unit.Described central control unit comprises PCB substrate and is located at the some control circuits on substrate, for controlling the operating state of each antenna oscillator 9.
Compared with prior art, this active antenna 100 have employed metal bearing plate 5, because metal inherently has conduction of heat, and the surface area ratio of metal bearing plate 5 is larger, therefore effectively heat dissipation problem can be solved, and large-sized radiation tooth need not be set, thus greatly reduce the size of cabinet, also namely reduce the size of this active antenna.
