Simulations using Computer Simulation Technology (CST) have been done on different pressure (10 Torr and 20 Torr) of Hg-Ar capillary tubes plasma antenna. The tubes which is small enough in diameter are designed as capillary plasma antenna, as well as a monopole antenna and also as an antenna arrays. They have been arranged into three different arrays with two different gap distances. The characteristics...
The design of plasma antenna array for Wi-Fi application, operating at 2.4 GHz is presented in this paper. Two pieces of fluorescent tube with same dimension of 586 mm length and 24.2 mm diameter was used for this plasma antenna. The antennas are arranged in two parallel side-by-side. The gap between two fluorescent tubes is 10 mm. Both tubes are filled with argon and mercury vapor. The proposed antenna...
A monopole plasma antenna for Wi-Fi application at 2.4 GHz was constructed using a commercially available fluorescent tube. The plasma antenna uses a fluorescent tube with length and diameter of 0.61 m and 0.025 m, respectively. The tube contains a mixture of argon and mercury vapor, which becomes conductive when sufficiently ionized into plasma state, allowing transmissions of radio frequency signal...
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...
