采用PSO算法的基站天线方向图综合优化

The Base Station Antenna Pattern Synthesis Optimization Using PSO Algorithm

随着当今社会手机的普及,基站天线也变得越来越重要,针对基站天线性能的提升也有各种方法,而基站天线的方向图综合优化设计是现今提高天线性能最常用的方法之一。无论是在设计之初还是在基站天线设置都需要根据其不同的环境与应用背景来设置相关参数以满足所需的电性能。本文采用高阶矩量法对板状振子型基站天线进行仿真计算,通过使用粒子群算法对其振子间距以及各个振子相位进行优化,实现了垂直面内较好的方向图综合设计。

With the popularity of mobile phones in today's society, the base station antenna has become more and more important, there are various methods for enhancing the performance of base station antenna and base station antenna pattern synthesis optimization design is nowadays one of the most commonly used method of antenna performance improve.Whether in the design or in the base station antenna setup needs to be based on its different environment and application background to set the relevant parameters to meet the required electrical performance.This article uses the simulative calculation of plate vibrator type base station antenna, the higher order moment method, by using the particle swarm optimization algorithm on the dipole spacin g and each oscillator phase optimization, realized in a vertical plane and good pattern synthesis design.
