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.
The design of a new kind of broad-band and wide-angle circularly polarized(CP) microstrip antennas is presented.Based upon the proximity coupling balance-feed by utilizing the capacitive probe,the 2 V standing wave ratio and wide-angle 3dB 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.
