Plasma antenna is a type of antenna that uses ionized gases as a conductor to receive
and transmit signal. The plasma antenna has the ability to focus on a single beam as
well as communicate in short pulses and can be configured in terms of frequency,
bandwidth, gain, length of column and radius of glass tube depending on the working
radio frequency. This research provides an analysis of effect of type of gas and
pressure on plasma antenna performance. It aims to study performance of each type
of selected gas and its variants in terms pressure as a plasma conductor to boost
signals through the coupling sleeve. The outcome of this research is specific
frequencies can be boosted by altering the pressure and type of gas. In reference to
Ne(5T) and Ar(5T & 10T), heavier atomic mass and increase of pressure of the same
element produces lower peak frequencies.
