Abstract
A beam-forming antenna system include a substrate; a plurality of mixers formed in the substrate; a phase generator formed in the substrate; and a plurality of antennas formed adjacent the substrate, wherein each mixer is coupled to a corresponding at least one of the antennas, and wherein the phase generator is operable to provide a plurality of uniquely-phased LO signals, each mixer being coupled to the phase generator to receive a different one of uniquely-phased LO signals such that an RF signal received by the antennas is phase-shifted through the mixers according to the unique phases of the LO signal to form a plurality of phase-shifted IF signals.
Claims6
An integrated beam-forming system, comprising:
- a substrate;
- a plurality of oscillators formed in the substrate;
- a phase generator formed in the substrate;
- and
- a plurality of antennas formed adjacent the substrate, wherein each oscillator is coupled to a corresponding at least one of the antennas, and wherein the phase generator is operable to provide a plurality of uniquely-phased reference clocks, each oscillator being coupled to the phase generator to receive a different one of the uniquely-phased reference clocks.
