Patent 7372412 was granted and assigned to Denso on May, 2008 by the United States Patent and Trademark Office.
The transceiver-integrated antenna includes an antenna element, a ground plate for grounding the antenna element, and a transceiver configured to transmit and receive radio signals through the antenna element. The transceiver is housed in a recess formed in the ground plate. The ground plate serves as not only a plane for grounding the antenna element, but also a radiator for dissipating the heat emitted from the transceiver.
