摘要

本文介绍了一种新型的Ku/Ka波段任意极化反射天线。反射单元由两种不同类型的单元组成:下带固定尺寸环的交叉偶极子单元和上带圆形补丁的环单元。此外，还对元件参数进行了优化，以抑制耦合效应。采用该元件模拟的双反射天线在16 GHz和35GHz时的增益分别为18.5 dB和24.9dB，下、上频段的孔径效率分别为38.21%和34.85%。

A novel ku/ka dual-band reflectarray antenna with arbitrary polarization

This paper describes a novel Ku/Ka band reflectarray antenna for operating at arbitrary polarization. The reflectarray elements consist of two different types of elements: cross-dipole element with fixed-dimension ring for the lower band, and the ring element with round patches for the upper band. Furthermore, the parameters of the element are optimized to suppress the coupling effects. The simulated radiation patterns of the dual-reflectarray antenna using the proposed element can show a gain of 18.5 dB at 16 GHz and 24.9dB at 35GHz with the aperture efficiency of 38.21% and 34.85% for the lower and upper band, respectively.
