摘要

本文提出了一种用于宽带反射光的双极化单晶片。通过调整结构的狭缝长度，可以实现两个极化的线性相位。设计了一种偏置反射镜，其中每个偏振光包含506个建议元件。仿真结果表明，在水平极化和垂直极化条件下，反射天线的1 db增益带宽分别为32%和31%。两种极化均获得了满意的副瓣和交叉极化特性。

Design of A Dual-Polarized Unit-Cell for Wideband Reflectarrays

In this article, a dual-polarized unit-cell for wideband refletarrays is presented. By tuning the slot length of the structure, a linear phase for both polarizations can be achieved. An offset-fed reflectarray containing 506 proposed elements for each polarization is designed. Simulations exhibit that the reflectarray antenna features a wide 1-dB gain bandwidth of 32% and 31% for horizontal and vertical polarization, respectively. Satisfactory sidelobe and cross-polarization behavior is also obtained for both polarizations.
