摘要

设计了一种新型双频双感圆极化方环槽天线。通过在接平面上刻两个方环形槽，改变其中一个槽对角线的间隙宽度，实现双频CP辐射。如果在微带馈线周围对称放置两个槽的微扰，则可以得到双义CP辐射。对所提出的天线进行了实现和测量。仿真和实测结果表明，该天线在两个谐振频率处具有良好的圆极化辐射。

A dual-band dual-sense circularly polarized square-ring slot antenna

A new dual-band dual-sense circularly polarized (CP) square-ring slot antenna is designed in this paper. By notching two square-ring slots in the ground plane, and changing the gap width in one of the diagonals of the two slots to achieve dual-band CP radiation. If the perturbations of the two slots are symmetrically placed about the microstrip feeding line, then a dual-sense CP radiation is obtained. The proposed antenna is implemented and measured. Simulated and measured results show that the antenna is with good circularly polarized radiations at the two resonant frequencies.
