Abstract – We describe the theory, practical construction, and experiments of a plasma antenna to radiate VHF wireless signals. The results show that a plasma antenna can be an effective radiator of RF signals with characteristics that favorably compare with a comparable metal antenna. Furthermore, when de-energized, the plasma antenna effectively disappears and thus can be useful when an object equipped with this antenna requires stealth (i.e., undetectable to RADAR). This paper provides a gentle introduction to plasma antennas for undergraduate physics and electrical engineering students who are studying general electromagnetic theory and basic antenna design. Building, measuring and characterizing a plasma antenna will enable experiential learning of not only the plasma antennas, but will also enhance the students’ knowledge of electrical conductivity, dielectric breakdown and quantum mechanics.
