摘要

本文提出了一种宽带可重构三极化超表面天线。它由双极化天线和可重构馈电网络组成。通过特征模态分析，设计了双极化天线。配置PIN二极管的馈电网络旨在控制双极化天线两种正交线性极化模式的相位差，实现45°线性极化（45°-LP）、右手圆极化（RHCP）和左手圆极化（LHCP）三种极化。测量结果表明，45°-LP的- 10 dB带宽为25.15%，RHCP为28.10%，LHCP为28.57%；RHCP的3 dB轴比带宽为23.96%，LHCP为23.54%。45°-LP时天线的峰值增益为9.7 dBi， RHCP时为8.66 dBi， LHCP时为9 dBi。

A Broadband Reconfigurable Tri-Polarized Metasurface Antenna Based on Characteristic Mode Analysis

In this letter, a broadband reconfigurable tri-polarized metasurface antenna is proposed. It consists of a dual-polarized antenna and a reconfigurable feeding network. The dual-polarized antenna is designed through characteristic mode analysis. The feeding network equipped with PIN diodes is intended to control the phase difference of two orthogonal linear polarization modes of the dual-polarized antenna, enabling three polarizations: 45° linear polarization (45°-LP), right-handed circular polarization (RHCP), and left-handed circular polarization (LHCP). The measurements reveal −10 dB bandwidths of 25.15% for 45°-LP, 28.10% for RHCP, and 28.57% for LHCP, as well as 3 dB axial ratio bandwidths of 23.96% for RHCP and 23.54% for LHCP. The peak gains of the antenna are 9.7 dBi for 45°-LP, 8.66 dBic for RHCP, and 9 dBic for LHCP.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
