Experience on plasma antenna technology

Plasma column antenna is a new technology for UHF/VHF communication. Except for theoretical research, creating a prototype with considerable performance as metal antenna is really very difficult. The plasma antenna research team of National Space Science Center has created some techniques to make a practical plasma antenna prototype, it can reach the same antenna gain and radiation pattern as a common metal antenna with relatively small size and power consuming. This paper presents our experience and problem solutions on plasma antenna research and manufacture.
