Reconfigurable Nested Plasma Antennas, Stacked Plasma Antenna Arrays, and Plasma FSS for Consolidated Apertures and Co-Site Interference Reduction or

Haleakala R & D, INC. will develop technology to address the effects and impacts of co-site interference with respect to the frequency range of : 30-88 MHz for SINCGARS, 116-174 MHz for VHF AM / ATC, 225-400 MHz element for UHF-AM / HAVEQUICK, 450-512 for Public Service, and 1200-2500 MHz for WNW / SRW. and achieve aperture consolidation. To reduce interference between the elements and facilitate collocated apertures, plasma antenna elements will be embedded (nested) within one another such that elements are RF transparent to frequencies outside their band of operation. Please see our website at: www.ionizedgasantennas.com where you can play a video of our smart plasma antenna as well read several articles. This improvement could be either increased gain to support higher data rates or increased bandwidth antennas to support multiple RF frequency bands. By using the same antenna for multiple frequency bands, the number of antennas located on a aviation and ground platforms can be reduced, thereby freeing up space for other critical capabilities to be co- located. If not co-located using plasma antenna nesting, plasma antennas in the system: 30-88 MHz for SINCGARS, 116-174 MHz for VHF AM / ATC, 225-400 MHz element for UHF-AM / HAVEQUICK, 450-512 for Public Service, and 1200-2500 MHz for WNW / SRW and can be separated on the aviation and ground platforms and even a small fraction of a wavelength apart without co-site interference.
