本文分析了目前国内外无线通信中心台中高增益全向天线的特点及其存在的同题。提出采用离散单元,特别是折合振子组成的阵列,得到较宽的频率特性及较高的增益,而且具有方向图可变的天线。给出了各种组阵方法的理论计算和实测结果 This paper analyzes the characteristics and existing problems of high-gain omni-directional antennas in Taichung at home and abroad at present. An array of discrete elements, especially the equivalent oscillator, is proposed to obtain wide frequency characteristics and high gain, and an antenna with variable directivity pattern. The theoretical calculations and measured results of various array methods are given
