Patent ID: 7830989

Claim:
A wafer scale radar antenna module (WSAM), comprising: a substrate, a plurality of antennas adjacent the substrate; an RF feed network adjacent the substrate, the RF feed network coupling to a distributed plurality of amplifiers integrated with the substrate, wherein the RF feed network and the distributed plurality of amplifiers are configured to form a resonant network such that if a timing signal is injected into an input port of the RF feed network, the resonant network oscillates to provide a globally synchronized RF signal to a plurality of integrated antenna circuits, wherein each integrated antenna circuit includes a corresponding subset of antennas from the plurality of antennas, and wherein each integrated antenna circuit includes a pulse shaping circuit having a plurality of selectable delay paths, each pulse shaping circuit being configured to rectify and level shift a version of the globally synchronized signal through selected ones of the selectable delay paths to provide a pulse train output signal; and a controller operable to control each integrated antenna circuit such that only selected pulses from the pulse train output signal arc transmitted through the integrated antenna circuit's subset of antennas to form transmitted pulses.
