We present a fast far-field phased array calibration/beamforming method. An improved version of the rotating-element electric-field vector (REV) method, which is used to calibrate array antennas by measuring the power received at a far-field point wh

A fully integrated passive true-time-delay (TTD) phase shifter is presented for a wideband phased array antenna using 28-nm CMOS technology. By using a delay-compensation technique, a linear phase characteristic is achieved within a wide frequency ra
