RF Radiation Behavior of Rare Gas in Plasma State

This paper analyzed the performance of monopole plasma antenna based on RF charging using different number of turns of coupling sleeve and different gases. The plasma antennas were designed with 3 different gases which are argon, nitrogen and fluorescent with pressure 10 Torr. For argon plasma antenna, different pressure was designed to analyze the performance of plasma antenna with pressure 0.5 Torr, 1 Torr, 5 Torr and 10 Torr. The dimension of discharge tube for argon and nitrogen is 130 mm length and 10 mm diameter, while for fluorescent 145 mm length and 12 mm diameter. The dimension of commercialize fluorescent were used as benchmark for other plasma antenna. The commercially fluorescent tubes contain mixture of vapour mercury and argon. 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 simulation by using CST Microwave Studio.
