Abstract

This paper presents an analysis of monopole plasma antenna performance using different number of turns of coil (as coupling sleeve). The plasma antennas were fabricated with 3 different gases which are neon, argon and xenon with pressure 0.5 Torr, 5 Torr and 15 Torr. The dimension of each tube is 130 mm length and 10 mm diameter. The plasma antennas were driven by radio frequency (RF) to sufficiently ionize the gas inside the tube to convert them into plasma state. Each antenna with different configuration of type of gas and pressure was tested while varying the number of coils turns. The antenna´s capability to operate as transceiver was verified through measurement of receiving signal power using a spectrum analyzer. It was found that 4 turns of the coil was optimum in each configuration.
