一种基于5—20kHz交流激励的U形等离子体天线
A U-shape plasma antenna based on excitation of 5m20 kHz alternating current power supply
摘要
Abstract
A U-shape plasma antenna is established by a 5--20 kHz alternating current(AC) source. The structure of the antenna is described, and part of electrical characteristics are measured. Results show that in a frequency range from 50 to 400 MHz, the noise level of 5--20 kHz AC plasma antenna is close to that of a metal antenna, but much lower than that of frequency AC plasma antenna. Besides, the antenna shows good impendance and gain bandwith characteristics.关键词
