摘要

提出了一种工作在ka波段的双层双模圆偏振反射天线。反射光由圆偏振喇叭中心馈电。对天线进行了数值分析。交叉槽阵元件采用角旋转技术进行相位补偿。在1.5 dB增益变化下，具有较高的孔径效率和16.5%的宽带增益带宽，具有良好的CP性能。

Ka-band dual mode circularly polarized reflectarray

A double layers dual mode circularly polarized (CP) reflectarray antenna operating in the ka-band is presented. The reflectarray is center fed by a circularly polarized horn. The antenna is analyzed numerically. Angular rotation technique for a crossed slot array element is used to make phase compensation. An excellent CP performance is achieved with high aperture efficiency and wide band gain bandwidth of 16.5 % for 1.5 dB gain variation.
