Open and Closed-Loop Weight Selection for Pattern Control of Paraboloidal Reflector Antennas with Reconfigurable Rim Scattering
R. Michael Buehrer, William W. Howard, Steven Ellingson
It has been demonstrated that modifying the rim scattering of a paraboloidal reflector antenna through the use of reconfigurable elements along the rim facilitates sidelobe modific…

Design of Rim-Located Reconfigurable Reflectarrays for Interference Mitigation in Reflector Antennas
Jordan Budhu, Sean V. Hum, Steven Ellingson +1
Radio telescopes are susceptible to interference arriving through its sidelobes. If a reflector antenna could be retrofitted with an adaptive null steering system, it could potenti…
