| 摘 要： | 本文提出一种新的宽带宽角圆极化微带天线设计方法,在利用容性探针近耦合馈电的基础上,通过平衡馈电,使贴片天线的阻抗带宽(VSWR≤2)和宽角轴比带宽(45°圆锥空域内的AR≤3dB)达到20%以上.实验测试表明,利用该方法设计的贴片天线的带宽达到26.33%(VSWR、宽角AR同时满足要求),从而证实了该方法的正确性和实用性.

| Abstract: | A new method for the design of broad-band and wide-angle circularly polarized (CP) microstrip patch antennas is presented in this paper.Based upon the proximity coupling balance-feed by utilizing capacitively probes,the 2 V standing wave ratio(VSWR) and wide-angle 3dB axial ratio (AR)(in the 45°conic airspace ) bandwidth can be achieved more than 20%.The measured results show that the wide-angle 3dB axial ratio and 2 V standing wave ratio bandwidth of the patch antenna designed by this method is 26.33%(VSWR≤2,wide-angle AR≤3dB).So this design technique is correct and practical. |
