摘要

设计了一种实用型宽频带圆极化微带天线，在容性探针顶部附加圆形贴片进行耦合馈电的基础上，通过平衡馈电提高了天线的阻抗带宽(VSWR<=2)和在宽角度内实现了圆极化(AR<=3 dB)．利用有限元积分软件CST对天线的参数进行优化仿真，通过实验测试表明：仿真与实测吻合较好，满足实际应用的需求．

Abstract

The design of a new kind of broad-band and wide-angle circularly polarized(CP)mierostrip antennas is presented．Based upon the proximity coupling balance-feed by utilizing the capacitive probe，the 2 V standing wave ratio and wide-angle 3 dB axial ratio(AR)are achieved．With the software of CST，the structure parameters of the antenna are optimized．The simulation results show that the antenna meets the requirements for application．
