Design and Fabrication of Plasma Array Antenna with beam forming

In this paper, the design and implementation of plasma antenna array with beam forming is discussed. The structure consists of a circular array of plasma tube enclosed in a unipolar UHF band monopole antenna. Beam forming is possible by the stimulated plasma tubes. The combination of the above antenna with plasma excitation controller makes the beam forming smart antenna. An experimental model in UHF band is fabricated that shows a good agreement between simulated and measured results.
