Abstract

In this article, a single-layer metasurface based reflector design is proposed for linear-to-linear cross-polarization conversion in microwave frequency range. The unit-cell of the proposed design consists of triple-arrow resonant design printed on a grounded FR4 substrate. Excellent cross-conversion is achieved over a broad frequency range (8.0-18.50 GHz) with polarization conversion efficiency higher than 90%. The proposed design has a large fractional bandwidth (FBW) of 80% due to three resonances occurring in the band. The polarization response is angularly stable with respect to oblique incidences with incidence angles up to 45°. The proposed design has been fabricated and experimentally validated. The measurement results are in good agreement with the simulation results.

摘要

本文提出了一种用于微波频率范围内线性到线性交叉极化转换的单层超表面反射器设计。所提出设计的单元由印刷在接地 FR4 基底上的三箭头谐振设计组成。在很宽的频率范围内（8.0-18.50GHz）实现了优异的交叉转换，极化转换效率高于 90%。由于在频带中出现了三个共振，因此该设计具有 80%的大分数带宽（FBW）。在 45°以内的斜入射角度下，极化响应具有角度稳定性。已经对该设计进行了制造和实验验证。测量结果与模拟结果吻合良好。
