Abstract
We present the first demonstration of a 2-D, true-time delay, transmit beamformer based on a novel technique that dynamically maps a 1-D beamformer´s output onto the input plane of an antenna array producing 2-D steering. This significantly reduces system complexity. The reconfigurable beamformer exhibits squint-free, /spl plusmn/70/spl deg/ azimuth and elevation steering over 4-20 GHz.
