Abstract
A system comprises a plurality of antenna elements arranged in a two-dimensional array, and a plurality of transmitter circuits communicatively coupled to the antenna elements, wherein the antenna elements and transmitter circuits are configured such that desired components of signals output by the plurality of transmitter circuits and radiated via the antenna elements coherently combine in a desired direction. Each of the transmitter circuits is operable to generate a corresponding second signal for transmission via a respective one of the antenna elements by shifting a phase of undesired components in the signal relative to a phase of desired components in the signal.
