摘要:
基于开口方形环频率选择表面(FSS),设计一款新型圆极化器,将线极化波转换为圆极化波.在圆极化器中加入串联双H型耦合枝节,利用有限元仿真软件Ansoft HFSS对圆极化器参数进行仿真和优化.结果表明:3 dB轴比的圆极化器带宽达到25.6%,其中,870~1 080 MHz频带内轴比都小于2 dB,S2,1都维持在-1.7 dB以上,圆极化器对馈源天线几乎不存在影响;相比于传统圆极化器,设计的圆极化器具有工作频带宽、结构层数少、模型简单及性能稳定等优点.
Abstract:
Based on split-rectangle-ring frequency selective surface(FSS), a novel circular polarization converter is designed which can convert linearly polarized wave into circularly polarized wave. This converter is with a H coupling stub. Then, the proposed converter parameters are simulated and optimized by finite element simulation software Ansoft HFSS. The simulation results show that its 3 dB axis ratio bandwidth reach 25.6%. Moreover, the axis ratio of proposed antenna is below 2 dB and the S2,1 is above -1.7 dB from 870 to 1 080 MHz. It means that the converter has little influence on feed antenna. Compared to the traditional converters, this circularly polarization converter has advantages like wide band, fewer layers, simpler structure, more stable performance and so on.
