Reconfigurable cylindrical plasma antenna

Abstract

This paper presents the performance of cylindrical plasma antenna. A plasma tube is used as radiating element. The antenna is designed and works at different frequencies. To couple electromagnetic signal from the coaxial probe to the plasma column, a coupling system is realized. It permits to excite the tube in order to have a monopole or dipole antenna. The performances of the cylindrical plasma antenna are given in terms of S11, gain and radiations patterns.
