Patent 8018375 was granted and assigned to Broadcom (company) on September, 2011 by the United States Patent and Trademark Office.
A projected artificial magnetic mirror (PAMM) radar device includes a transceiver module, a shaping module, and an antenna structure. The antenna structure includes a plurality of metal patches, a metal backing, a dielectric material, and one or more antennas. The metal patches are electrically coupled to the metal backing to form an inductive-capacitive network that, for the one or more antennas and within a given frequency band, substantially reduces surface waves to obtain a detectable angle of incidence of approximately ninety degrees.
