The present invention has following advantage compared with the prior art:
1. entire antenna array and matching network adopt the processing technology one-shot forming that printed board light is painted, and have increased the antenna consistency, stability and good electrical properties.
2. when downwards bevel beam and wave beam forming, the present invention has higher precision, and easier realization.
3. owing to adopt little band matching network to replace short branch, reduce the difficulty that standing wave is adjusted effectively, and guaranteed the consistency of standing-wave ratio, and realized the function of coupling and DC earthing simultaneously.
Summary of the invention:
The objective of the invention is to solve deficiency of the prior art, provide a kind of microstrip conductor and micro-strip oscillator as radiating element, microstrip network is as matched feed network, the one-time formed a kind of little band omnidirectional antenna that is used for mobile communication of processing technology that entire antenna array and matching network adopt printed board light to paint.
Above-mentioned a kind of little band omnidirectional antenna that is used for mobile communication, comprise little band radiation shake row 1, microstrip conductor 2, microstrip-fed line 3, little band matching network 4, little band earth connection 5 and coaxial electrical cable end 6, the entire antenna array connects as one by the metallization via hole, paint by printed board light the various piece in the aerial array is coupled together, last coaxial electrical cable end 6 is connected with aerial array by the mode of welding again.
Above-mentioned little band omnidirectional antenna, wherein little band radiation row 1 little band radiation row 1 two ends that shake that shake are left end radiation arm 12 and right-hand member radiation arm 13, microstrip conductor 2 on the left end radiation arm 12 is connected with little band earth connection 5 by metallization via hole 14, and right-hand member radiation arm 13 is connected with microstrip-fed line 3 by metallization via hole 8
