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 popularization of mobile phones in today’s society, the base station antennas have become more and more important. There are various methods for improving the performance of the base station antennas. The integrated optimization design of the base station antennas is one of the most commonly used methods for improving antenna performance today. Whether it is at the beginning of the design or in the base station antenna settings need to be set according to their different context and application background to set the relevant parameters to meet the required electrical performance. In this paper, the high-order moment method is used to simulate the plate-shaped oscillator base station antenna. By using the particle swarm algorithm to optimize the oscillator spacing and the phase of each oscillator, a better integrated design of the directional pattern in the vertical plane is achieved.
