A Brief Study on Reconfigurable Plasma Antennas

Abstract

This paper study the reconfigurable characteristics of monopole plasma antennas. Plasma antennas use partially or fully ionized gas instead of metal as the conducting medium to create an antenna. The advantages of plasma antennas are that they are highly reconfigurable and can be turned on and off. The radiated wave profile can be calculated by several numerical methods. The disadvantage is that plasma antennas require energy to be ionized. This paper presents a basic study on plasma monopole antenna using a single fluorescent tube antenna The reconfigurable characteristic of the monopole plasma antenna and its array are analyzed through the simulations. The reconfigurable results of the working frequency and the radiation pattern of the monopole plasma antenna are obtained, the reconfigurable characteristic of the four-element and six-element of the plasma antenna array are analyzed
