短波双极天线应用方法研究

Research on Application of Short-wave Dipole Antenna

双极天线是一种常用的短波天线,该天线对不同来波方向的电磁波的接收具有方向性。在组网中存在多家电台时,很难保证所有电台的来波都有最佳的接收角度,从而导致通信质量下降。通过分析双极天线上电流(或场)与来波方向的关系,在求得该函数近似解的基础上,通过数学仿真,立足实际应用情况,探讨双极天线的另类架设方法,使得组网通信效果更佳。

Dipole antenna is one kind of common short-wave antenna,and it has directionality for receiving of electromagnetic waves from all direction.But it＇s difficult to make sure that all stations have the best receiving angle when there are many stations on net,so the quality of communication will be on a low level.This paper gets an approximate solution by analyzing the relation between the angle of receiving waves and the current of dipole antenna.And it discusses the method of mounting the dipole antenna to make the quality of communication better by math simulation and practical application.
