以前火箭用的甚高频天线多半使用其长约为1/4波长的天线。因而,当频率变低时,则天线变长,对于火箭来说使用大型的天线是不适宜的。此外,大型天线意味着天线重量的增加,要限制天线的重量,往往又会出现抗振动、冲击性能差的缺点。这样,以提高甚高频天线的小型、轻量化和抗干扰特性为目标,对一端短路,另一端以电容器作为终端的传输线型天线,进行了实验、解析、及实用试制。
Most rocket antennas used before the antenna is about its length of 1/4 wavelength. Therefore, when the frequency becomes lower, the antenna becomes longer, and it is not suitable for the rocket to use a large antenna. In addition, a large antenna means an increase in the weight of the antenna. To limit the weight of the antenna, there are often shortcomings of anti-vibration and poor impact performance. In this way, experiments, analysis, and practical trial production of a transmission line type antenna with a short circuit at one end and a capacitor at the other end with the aim of improving compact, lightweight and anti-interference characteristics of the VHF antenna were carried out.
