Sidelobe Canceling for Reconfigurable Holographic Metamaterial Antenna

Accurate and efficient methods for beam-steering of holographic metamaterial antennas is of critical importance for enabling consumer usage of satellite data capacities. We develop an algorithm capable of optimizing the beam pattern of the holographic antenna through software, reconfigurable controls. Our method provides an effective technique for antenna pattern optimization for a holographic antenna, which significantly suppresses sidelobes. The efficacy of the algorithm is demonstrated both on a computational model of the antenna and experimentally. Due to their exceptional portability, low-power consumption, and lack of moving parts, holographic antennas are an attractive and viable technology when combined with proven software-based strategies to optimize performance.
