Another object of the present utility model is to provide a kind of active antenna, comprise above-mentioned cabinet, be located at the antenna assembly in cabinet, for the control device of control antenna device operating state, and to be connected with described control device and for realizing the external interface that this active antenna is connected with external equipment, described antenna assembly comprises reflecting plate and is fixed on several antenna oscillators in reflecting plate one side, reflecting plate another side is located at by described control device, this control device comprises the central control unit be electrically connected with described antenna oscillator and the power supply of powering for described central control unit, described reflecting plate and described metal bearing plate fix.
Described side plate is the side plate that metal material is made, and to improve the radiating effect of this active antenna further, strengthens the intensity of cabinet simultaneously.
The height of described side plate lower than the height of described reflecting plate, to avoid causing harmful effect to the covering effect of signals of this active antenna.
Further; one end of described reflecting plate is located at by described control device; described metal bearing plate, in the position corresponding to described control device, offers the Operation and Maintenance window matched with described control device, is established after described control device protrudes from described Operation and Maintenance window by a protection clamshell.Staff need not open whole bearing plate, only can need be operated control device by Operation and Maintenance window, easy to operate, save time.
This active antenna also comprises the installation fitting for this active antenna being fixed on position to be installed, and described installation fitting is threaded connection part and is connected with described metal bearing plate.

[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.
Further, described side plate 3 is made up of metal material, and such as described side plate 3 can be the aluminium alloy plate that rigidity is larger, to improve intensity and the wind loading rating of this active antenna 100 further.In addition, the side plate 3 that metal material is made also accelerates the radiating effect of this active antenna 100 to a certain extent.
The covering effect of signals of side plate 3 to this active antenna 100 made to prevent metal material causes harmful effect, and the height of described side plate 3 is preferably lower than the height of described reflecting plate 15.
Further; for the ease of debugging and maintenance; one end of described reflecting plate 15 is located at by described control device 30; and described metal bearing plate 5 offers Operation and Maintenance window in the position corresponding with described control device 30 (schemes not show; lower same), and a containment vessel 7 is added a cover on this Operation and Maintenance window.
When debugging (or maintenance) to this active antenna 100, staff opens described containment vessel 7, can debug (or maintenance) operation by Operation and Maintenance window to control device.Due to whole metal bearing plate 5 need not be opened, can operate by means of only Operation and Maintenance window, more convenient to operate, save time, also can avoid opening metal bearing plate 5 completely and antenna assembly being brought to the adverse effect that may exist.
Further; in order to reduce this active antenna 100 thickness and and for the ease of operation; described Operation and Maintenance window matches with described control device 30 and arranges; described reflecting plate 15 is adjacent to described metal bearing plate 5 and installs, and is covered establish after described control device 30 and external interface 8 protrude from described Operation and Maintenance window by described containment vessel 7.
