A plasma antenna includes a plasma column formed of an ionizable gas. A
modulating carrier frequency produces Hertzian dipoles within the plasma
that radiate RF energy at the modulating carrier. The antenna, which
produces these dipoles, can be short and still produce significant gain
when the modulating carrier frequency and the natural resonance frequency
of the plasma are substantially equal. Other aspects of the invention
include a method to produce such plasma antenna and a product by process
embodiment of the plasma antenna.
