Abstract: SARA proposes a family of innovative broadband, low-profile, and potentially surface-conformal antennas especially-applicable to newly-emerging frequency-agile or waveform-agile 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 and permit the confident design of compact configurations offering superior performance across bandwidths spanning frequency ranges of interest. SARA proposes to build-upon and advance this technology to deliver practical designs to ONR and, as the work progresses, to build prototypes and perform demonstrations of one or more antenna prototypes operating under full rep-rated conditions at peak powers exceeding 100 MW.
Benefits: The proposed technology is expected to have multiple defense-related applications in fieldable integrated DEW platforms and in laboratory systems used for HPRF effects testing. When operated at more conventional power levels, these high aperture-efficiency antennas could simplify execution of some types of commercial electro�mag�netic compatibility (EMC) tests, reducing or even eliminating the need for expensive supplemental power amplifiers.
