Compact, Collapsible, or Conformal Antenna Design for Emerging High Power Radio Frequency (HPRF) Sources

SARA proposes to advance a family of innovative broadband, low-profile, and potentially surface-conformal antennas that are especially-compatible with newly-emerging HPRF sources. The proposed antennas are notable for their non-resonant characteristics and transmission-line fed, high aperture-efficiency, high peak-power capable apertures. Analyses based on modern full-wave RF numerical models demonstrate the feasibility of our approach to meeting ONRs demanding requirements, including superior performance across the frequency ranges of interest and supporting fully rep-rated conditions at peak powers exceeding 100 MW. SARA proposes a methodical and low-risk Phase II programbuilding directly upon the technology established in Phase Ito design, fabricate, characterize, and deliver these fully-functional HPRF antennas to the government.
