In this paper, frequency and polarization reconfigurable patch antenna is presented. The designed antenna has a simple structure and compact size of 40 × 40 × 2.5 mm³. Frequency reconfiguration is achieved by using PIN diode while switchable truncated corners of the patch antenna are for linear-to-circular polarization reconfiguration. The proposed antenna structure is designed for global navigation satellite system L1 band (1.589–1.605 GHz), wireless local area network at 2.4 GHz band, worldwide interoperability for microwave access at 2.5 GHz band and mobile satellite communication systems at 1.6 GHz frequency band.

简单的频率和极化可重构天线

本文提出了频率和极化可重构贴片天线。设计的天线结构简单，尺寸紧凑，仅为40×40×2.5 mm ³。频率重新配置通过使用PIN二极管实现，而贴片天线的可切换截断角用于线性至圆极化重新配置。拟议的天线结构设计用于全球导航卫星系统L1频带（1.589-1.605 GHz），2.4 GHz频带的无线局域网，2.5 GHz频带的微波访问的全球互通性以及1.6 GHz频带的移动卫星通信系统。
