Movable Superdirective Antenna Pairs for Phase-Shifter-Free mmWave Beamforming
An mmWave receive-array design that groups antennas into strongly coupled superdirective pairs whose rotation angle and position are mechanically adjustable, so the array can direct superdirective gain toward multipath signals and maximize SNR without any phase shifters or attenuators. Students learn how mechanical antenna reconfiguration plus a non-convex joint optimization can replace costly RF beamforming hardware while preserving scanning bandwidth.
