ABSTRACT 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.

一种简单的频率和极化可重构天线

摘要 在本文中，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，为40×40×2.5 mm3。频率重构是通过使用 PIN 二极管实现的，而贴片天线的可切换截角用于线性到圆极化重构。提议的天线结构专为全球导航卫星系统 L1 频段（1.589-1.605 GHz）、2.4 GHz 频段的无线局域网、2.5 GHz 频段微波接入的全球互操作性和 1.6 GHz 频段移动卫星通信系统而设计。
