Embodiment
For describing technology contents of the present utility model, structural feature, the purpose that realizes and effect in detail, below especially exemplified by embodiment and cooperate accompanying drawing to give in detail explanation.
See also Fig. 1 to Fig. 3, it has disclosed a specific embodiment of the bidirectional oriented domestic aerial of the utility model.In the present embodiment, this bidirectional oriented domestic aerial comprises housing 10, is arranged at the dual polarization vibrator 20 in the housing 10 and two feeder lines 30 that are connected with dual polarization vibrator 20.
Two feeder lines 30 are separately fixed on the substrate 210, and each feeder line 30 divides plate to be divided into two-way by a merit, the earth connection on each road is welded on the edge of a fluting 221, the holding wire on this road is welded on another edge of corresponding fluting 221, thereby two feeder lines 30 be divided into four the tunnel respectively with 221 welding of four flutings, so dual polarization vibrator 20 is shot out by the signal amplitude of four flutings 221 with difference polarization.
Because the bidirectional oriented domestic aerial of the utility model covers metal level 220 to the both sides radiation signal by side cover 120 with at substrate 210, thus the bidirectional oriented domestic aerial of the utility model can simplified structure, reduce volume.
See also Fig. 4 and Fig. 5, it has disclosed another specific embodiment of the bidirectional oriented domestic aerial of the utility model.In the present embodiment, this bidirectional oriented domestic aerial comprises housing 10, is arranged at two feeder lines 30 of dual polarization vibrator 40 to be connected with dual polarization vibrator 20 in the housing 10.The structure of the present embodiment housing 10 is identical with the structure of last embodiment housing 10, does not repeat them here.
In four radiation fins 430 two are arranged in the two adjacent flutings 421; Two radiation fins 430 are arranged on the opposite side of substrate 410 and are arranged in addition two fluting 421 places in addition, and the projection at metal level 420 of these two radiation fins 430 falls in the corresponding fluting 421 respectively.Be arranged on two radiation fins 430 of fluting in 421 and link together with the mode of the corresponding radiation fin 430 that is arranged on substrate 410 opposite sides by via hole respectively, thus formation slot-coupled and signal amplitude is shot out between the edge of radiation fin 430 and fluting 421.
In addition, welding for the ease of two feeder lines 30, in the present embodiment, dual polarization vibrator 40 also comprises two shape braces 440 that are " L ", what this two brace 440 was arranged on substrate 410 is provided with the relative opposite side of metal level 420 1 sides, and the mode of two braces 440 by via hole respectively be arranged on corresponding fluting 421 in radiation fin 430 be connected.
Because dual polarization vibrator 40 covering metal layer 420 on substrate 410 of the bidirectional oriented domestic aerial of the present embodiment, offer fluting 421 on the metal level 420, and link together in twos in four radiation fins 430, then form the mode radiation signal of slot-coupled between the edge by radiation fin 430 and fluting 421, therefore two feeder lines 30 needn't weld with dual polarization vibrator 40 by mixer, and each feeder line 30 only needs a solder joint to be connected with dual polarization vibrator 40, thereby can be easy to regulate impedance matching.Therefore the dual polarization vibrator 40 of the bidirectional oriented domestic aerial of the present embodiment is when reducing volume, and is can the subtrahend amount few, reduce and regulate the impedance matching difficulty.
Certainly, although the dual polarization vibrator 40 of the bidirectional oriented domestic aerial of the utility model can solve existing domestic aerial complex structure, the problem that volume is larger, however it not only can be used for domestic aerial, and it is changed a little, and it also can be used for outdoor antenna for base station.
Abovely in conjunction with most preferred embodiment the utility model is described, but the utility model is not limited to the embodiment of above announcement, and should contains various modification, equivalent combinations of carrying out according to essence of the present utility model.
