摘　　要：提出了一种共面波导馈电的新型宽带圆极化方形缝隙天线,在地板上的对角上加载E型缝隙激励宽带圆极化辐射,并采用加载L型缝隙,以及在馈线中开缝隙来改善天线的圆极化性能。仿真结果表明,天线的3 d B轴比带宽可达到39.26%,回波损耗小于-10 d B的阻抗带宽可达63.29%。A novel broadband circularly polarized（ CP） antenna with E-shaped structure in the two opposite corners in the ground plane is proposed in this paper. The antenna is fed by coplanar waveguide. The CP property could be improved by L-shaped structure and slots in the feeding part. The simulated results show the proposed antenna has a synthetic bandwidth 39. 26% with 3 d B AR and the impedance bandwidth 63. 29% with S11〈 -10 d B.
