Through theoretical analysis and experimental testing ASI will ascertain the suitability of using gas plasma to develop a high-powered, reconfigurable antenna operating in the S and X-bands of the electromagnetic spectrum. This design concept would be used to detect and track ballistic missiles. We will use a "windowing effect" that will enhance directivity, suppress back and side lobes, mitigate EMI and increase radiation efficiency. We believe this unique and innovative design will allow development of multi-functional, multi-spectral plasma array antennas capable of operation in two disparate areas of the electromagnetic spectrum from a single aperture. We intend to show that by controlling plasma density and pressure a highly reconfigurable plasma array antenna can be developed.Gas plasma antennas with their features of reconfigurability, stealth, efficiency, multifunctionality, flexibility and anti-radiation features could be designed for a multitude of communication applications. Waveguides could be made from plasma tubes thereby reducing weight, installation costs and transmission complexities in antenna systems designs. In addition cellular phones could be enhanced by the insertion of a plasma shield to protect the brain from electromagnetic radiation. In the RF world plasma parabolic antennas could be designed to operate much the same as metal ones.
