Flexible Beam Design for Vital Sign Monitoring Using a Phased Array Equipped With Double-Phase Shifters

Recognizing the low-cost advantage of phased arrays, we investigate the improvement of the beamforming capability of a phased array via the use of double-phase shifters (DPS), i.e., each antenna is fed with the sum of the outputs of two phase shifters. The use of DPS allows for the manipulation of b…
