摘要

展望了一种具有双向辐射方向图的宽带双CP小型化圆槽天线的设计。该天线由一个月形开口组成，以实现超波段CP性能。双数目50欧姆微带线以半月形排列端口结束，在规定带宽内实现RHCP和LHCP。通过在地面布置中引入切割槽，并将输入激励与满月缝偏移较小，显著提高了ARBW。对投影天线进行了仿真。-10dB的模拟RL约为(0.75~14.0 GHz)频段和0.65~6.45 GHz (ARBW为3dB)， ARBW内S21>24.25dB。

Design of a Circular Slot Antenna with Broadband Dual CP Bi-directional Radiation Pattern

Design of a miniaturized Circular Slot Aerial with Broadband Dual CP with Bi-Directional Radiation pattern is anticipated. This aerial consists of a moon shaped opening to accomplish superband CP performance. Dual number of 50 ohms micro strip line ended with a half-moon arrangement ports to realize both RHCP and LHCP in the specified bandwidth. The ARBW is expressively increased by introducing cutting slot in the ground arrangement and shifting the input excitation to little offset from the full moon slit. The projected aerial is simulated. The simulated RL of -10dB is about (0.75~14.0 GHz) band and 0.65~6.45 GHz (ARBW of 3dB) and the S21>24.25dB within the ARBW.
