Analysis and design of plasma monopole antenna

“…A plasma antenna is researched and measured in [1], and radiation characteristics are similar to metal antenna when signal is transmitted and received. The structure parameters and current distribution of a plasma antenna are researched in [2][3][4], and radiation efficiency of the antenna is about 25%. Experiments of electron density distribution, radiation patterns and noise characteristics are analyzed in [5][6][7].…”

Reconfigurable antenna using plasma reflector

“…One of the earliest realization of plasma as radiator has been carried out for 112MHz in [11]. Later on, in [12][13] came out with experimental results for UHF and VHF band. The selection of excitation techniques also has been actively studied by many research groups [4][5][6][7]14].…”

Beam-Forming and Beam-Steering Capabilities of a Reconfigurable Plasma Antenna Array

“…In particular, a Gaseous Plasma Antenna (GPA) consists of a plasma discharge confined in a dielectric tube which may come in different shapes, e.g., loops or rods. On the other hand, depending on the intended application, the plasma can be generated by feeding EM power through various methods, e.g., direct-current (DC) discharge or Radio Frequency (RF) surface-waves [8,9].…”
