INTRODUCTION
Plasma antennas are radio frequency antennas that employ plasma as the guiding medium for electromagnetic radiation.Here, plasma discharge tubes are used as the antenna elements. the tubes become conductors when they are energised and can transmit and receive radio signals. And they revert to non-
conducting elements when de-energized. In this state they do not reflect
probing radio signals.Plasma antenna can be "Steered" electronically. It can also be turned off rapidly reducing the effect of ringing on pulse on transmission.
PLASMA ANTENNA TECHNOLOGY
The antenna design has been an integral part of virtually every communication and radar application. For all kinds of applications which range from general broadcast of radio frequency signals for public use to complex weapon systems, there are specialized antennas available. Plasma antenna technology employs ionized gas enclosed in a tube (or other enclosure) as the conducting element of an antenna.Whereas the conventional antennas use solid metal wires as the conducting element. The design allows for extremely short pulses, important to many forms of digital communication and radars.compact and dynamically reconfigurable antennas are produced easily with this technology.
