A beam-forming antenna system includes an array of integrated antenna circuits. Each integrated antenna circuit 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. In an alternative embodiment, the phasing to each antenna element is controlled through a fixed corporate feed network. The relative gains of the antenna signals received or transmitted through the fixed corporate feed may be adjusted with respect to each other to provide a beam steering capability.
