一、概述要弄清蝙蝠翼天线工作原理,首先要从翼振子翼片结构谈起,由图1可知,翼片由一根直撑D-A-D和七根振子AF、BF_1、CF_2、DF_3构成,且翼片由A点馈电(即始端)D点接地(即终端短路),通常取D-A-D-λ/2,即AD=λ/4,要真正掌握蝙蝠翼天线基本原理,关键问题就在于将AD看成λ/4短路线,其它各个振子看成λ/4开路线且两者合为一体,据此分析问题就迎刃而解了。 First, an overview To understand the bat wing antenna working principle, we must first talk about the wing oscillator wing structure, from Figure 1 shows that the wing consists of a straight support DAD and seven oscillator AF, BF_1, CF_2, DF_3 constitute, and The wing is fed from the point A (ie, the beginning) to point D (ie, the terminal is short-circuited). Usually DAD-λ / 2 is taken as AD = λ / 4. To master the basic principle of batwing antenna, As a λ / 4 short-circuit, the other each oscillator as λ / 4 open circuit and the two together, according to the analysis of the problem to be solved.
