基于矩量法的小型化宽带线天线的仿真研究

Simulation and Research of Wideband Small Linear Antenna Based on MOM

研究了线天线的宽带化和小型化问题。针对目前通信技术的发展,各种电子设备均向小型化与微小型化方向发展,多频段和宽带跳频对带宽的需求,而常用的双极子天线由于带宽窄和物理尺寸大,无法满足天线小型化和宽带化的要求。提出了宽带匹配网络与加载相结合的方法设计了一种单极子加载天线,通过仿真详细分析了天线的电压驻波比和辐射特性,得出这种单极子加载线天线全面提高天线增益和降低电压驻波比的结果,经实验证明单极子加载天线基本满足小型宽带线天线要求。

This paper studies the broadband and miniaturization of wire antennas.As the development of communication technology,the miniature and wideband of equipment become more important than before,and so do multiband and broadband frequency hopping to the requirements of bandwidth.In order to resolve the problem of existing narrow bandwidth and the physical size of the antenna,this paper combines a broadband matching network with loaded technology.The gain of this monopole loaded wire antenna is improved and the voltage standing wave ratio is reduced via the simulation of a detailed analysis of the antenna VSWR and radiation pattern.The experiment shows that the monopole antenna loaded broadband wire antennas basically meet the needs.
