Radiation pattern synthesis for a prolate spheroidal antenna
2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2017An antenna is designed consisting of axial surface currents on a prolate spheroidal metallic surface. The dual orthogonality of the prolate spheroidal wave functions is utilized to synthesize a far field radiation pattern which best approximates a desired far field pattern for a given arbitrary superdirective ratio.

FSS based Radiation Pattern Decorrelator for MIMO Antenna
2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2018This work presents a novel technique to reduce the correlation coefficient between adjacent antenna elements in a multiple-input-multiple-output (MIMO) configuration. The proposed technique utilizes a phase-gradient frequency selective surface (FSS) as a superstrate in a Fabry-Perot cavity configuration, which tilts the beam of individual elements in ...
