摘要
文中给出了一种基于高仰角的,体积小,携带方便的环形天线,用于解决短波便携通信中近距离短波无盲区的通信问题。对天线工作原理,天线效率以及天线辐射方向图进行了研究,并制作与测试了该天线的性能,在近距离无盲区通信系统中有着比鞭天线更好的优势,有着很高的实用价值。
This paper describes a small and portable loop antenna based on high elevation angle, which may solve the problem of short-distance HF no-blind zone communication in HF portable communication. It discusses the working principle, the efficiency and the radia- tion pattern of such antenna, makes one antenna and tests its performance. The paper shows this antenna is better than whip antenna in short-distance no-blind communication system, and has high practical value.
