This paper is intended to the study of antenna parameters of plasma antennas to help the optimization of plasma antenna dimensions (radius and length). To accomplish this, three configurations of plasma antenna are simulated. The observations are taken on variations in the antenna parameters with the different radius and length of the plasma column. Additionally, to acquire similarity with metallic antenna, three models of metallic (copper) antenna are also be simulated with same configurations

Results suggest, the plasma antenna and metallic antenna are showing similar radiation patterns for each types of modals and at all the resonance frequencies, however the resonance frequencies and gain are different for different configurations of plasma antennas. The plasma antenna has become very useful applications in the field of communication and this paper provide important information about the antenna parameters of plasma antenna, along with the comparative study of antenna parameters with the metallic antenna. The paper deals with the different resonance frequencies of plasma antenna and hence reports about the re-tunability of plasma antenna as well.
