本文对 Delta 天线的方向特性进行了研究,推导了 Delta 天线 H 面和 E 面的方向性函数的计算公式,绘出了方向图的理论曲线和实验曲线;用实验的方法测得驻波比曲线。由分析可知行波 Delta 天线是短波波段中短距离通信的较为理想的一种天线型式。
In this paper, the directional characteristics of Delta antenna are studied, and the formula of directivity function of H antenna and E-plane of Delta antenna is deduced. The theoretical curve and experimental curve of the directional antenna are plotted. The experimental results show that the VSWR curve . It can be seen from the analysis that the traveling wave Delta antenna is an ideal antenna type for short-range communication in the short wave band.
