摘要

提出了一种紧凑的高隔离双极化印刷天线。所提出的双极化天线结构非常简单,即垂直极化采用cpw馈电开槽单极子,水平极化采用微带馈电开槽贴片。给出了表面电流分布,分析了极化分异的机理。讨论了工作在3.5 GHz频段的原型设计。仿真和实测结果表明,该天线具有低包络相关和高端口隔离(>25dB)的特点。

A Compact Dual-polarized Printed Antenna Based on Slotted Patch
A compact dual-polarized printed antenna with high isolation is presented. The proposed dual-polarized antenna has a very simple structure, which is a combination of a CPW-fed slotted monopole for vertical polarization and a microstrip-fed slotted patch for horizontal polarization. Surface current distributions are given to analyze the mechanism of polarization diversity. A prototype design operating at 3.5 GHz band is discussed. Simulated and measured results show that the proposed antenna has low envelope correlation and high ports isolation (>25dB).
