摘要

本文提出了一种基于天线滤波天线(AFA)结构的双频线圆极化变换器元件。该电池的特点包括薄的三层结构和在两个非相邻频段将线性入射波转换为两个正交圆偏振的能力。这种物理和电气规格的结合使这种电池成为一种新颖的解决方案。该小区的一个例子适用于卫星通信，设计工作在20GHz和30GHz(卫星ka波段)，带宽分别为4%和8%。

Antenna-filter-antenna-based cell for linear-to-circular polarizer transmit-array

In this paper, we propose a dual-band linear-to-circular polarization converter element based on the antenna-filter-antenna (AFA) structure. The traits of this cell include thin three-layer structure and ability to convert a linear incident wave to two orthogonal circular polarizations at two non-adjacent frequency bands. This combination of physical and electrical specifications makes this cell a novel solution. An example of this cell suitable for satellite communication is designed to operate at 20GHz and 30GHz (satellite Ka-band) with 4% and 8% bandwidth, respectively.
