A Novel Design Method for High-Efficiency Quasi-2-bit Reconfigurable Metasurface Antennas

This communication proposes a novel design method for a quasi-2-bit reconfigurable metasurface antenna (RMA) to improve aperture efficiency using a simple bias circuit. The quasi-2-bit RMA is designed by combining two types of 1-bit unit cells to achieve four quantized phase states, which results in...
