Patent ID: 8018375

Claim:
A projected artificial magnetic mirror (PAMM) radar device comprises: a transceiver module operable to: generate an outbound wireless signal based on an outbound control signal; and convert the inbound wireless signal into an inbound message; a shaping module operable to: produce one or more transmit shaped signals based on the outbound wireless signal and operational parameters; and produce one or more inbound wireless signals based on one or more receive shaped signals and on the operational parameters; an antenna structure including: a plurality of metal patches on a first layer of a substrate; a metal backing on a second layer of the substrate; a dielectric material between the first and second layers, wherein the plurality of metal patches is electrically coupled to the metal backing to form an inductive-capacitive network that, for a third layer of the substrate and within a given frequency band, substantially reduces surface waves along the third layer to obtain a detectable angle of incidence of approximately ninety degrees; one or more antennas on the third layer of the substrate, wherein the one or more antennas: transmits the one or more transmit shaped signals as an outbound radar signal; and receives the one or more receive shaped signals as an inbound radar signal.
