全向宽带多极化天线的设计

Design of Omni-Directional Wideband Multi-Polarization Antenna

针对军民两用机场对不同极化方式电台天线的新需求,本文介绍了一种全向宽带多极化天线,该天线由多个倾斜天线阵元组成,具备宽频带、多极化及全向辐射等特点。文中分析了不同倾斜角度对天线H面水平极化增益与垂直极化增益的影响。仿真结果表明,天线在不同极化增益配比下具备良好的全向辐射特性。

In response to the new needs of dual-use airports for radio antennas with different polarizations,an omnidirectional wideband multi-polarization antenna is introduced in this paper.The antenna is composed of a plurality of tilted antenna arrays,with broadband,multi-polarization and omni-directional radiation characteristics.The paper analyzes the influence of different tilt angles on the horizontal polarization gain and vertical polarization gain of the H plane,the simulation results show that,the antenna has good omnidirectional radiation characteristics under different polarization gain ratios.
