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...
A monopole plasma antenna with cylindrical parabolic reflector is proposed. A cylindrical parabolic reflector is placed at the back side of focusing signal to reflect the signal received from transmitter back to the front for increased antenna directivity. The purpose of this design is to enhance the antenna gain and produce strong antenna signal. A monopole plasma antenna positioned at the center...
This paper presents of analysis the performance monopole antenna with fluorescent tubes. The antenna was designed at the operating frequency which is 4.9GHz. The fluorescent tubes consist of a glass tube filled with mixture mercury vapor and argon gas. After get sufficient voltage the gas inside the tube will ionize to plasma and formed plasma column. The plasma frequency is equal to 5.634e11. The...
This paper design on plasma monopole antenna and to prove that a plasma column has been characterized as an antenna. The dimension of the antenna in this project is length of the plasma column l= 150mm, the radius of plasma column r = 5.2mm and the ground for this antenna using an aluminum. The radius for circular aluminum is 40mm. The frequency target range 550MHz until 600MHz. This frequency can...
