Abstract

A beam-forming antenna system includes an array of integrated antenna units. Each integrated antenna unit includes an oscillator coupled to an antenna. A network couples to the integrated antenna units to provide phasing information to the oscillators. A controller controls the phasing information provided by the network to the oscillators
