Abstract :
A half-duplex self-steering array using power detection and phase shifting is presented. The system combines a phase-shifting array and an RF power-tracking control circuit to autonomously steer its beam toward the peak-power direction. Retrodirectivity is reported for angles of 0Ð, −15Ð, −30Ð, and +45Ð at a transmitting frequency of 6.5 GHz.
