Ka-Band Rotman Lens-Based Retrodirective Beamforming System for Wireless Power Transfer
نویسندگان
چکیده
A retrodirective beamforming system (BFS) based on a Rotman lens is proposed for far-field wireless power transfer at Ka-band. The true-time-delay property of the allows wideband operation covering 28–38 GHz. designed BFS comprises with nine beam ports connected to nine-element linear Vivaldi array. implemented using PCB technology ease manufacturing and low-cost processing. simulated measured results demonstrate that can generate discrete beams over scan range ±45° wide impedance bandwidth.
