Publication number: 20090231204Abstract: An antenna and a method for direct matching the antenna to a transceiver is provided. The method includes designing the antenna to directly match an antenna impedance to at least one of an input impedance of the transceiver and an output impedance of the transceiver. The step of designing includes modeling the antenna and the transceiver and implementing an electromagnetic field simulation using a human body phantom model with the antenna to determine the value of an antenna parameter for the antenna model. The antenna for a communication device having a transceiver, includes an antenna element directly coupled with the transceiver having a transmitter and a receiver, an antenna parameter of the antenna element being tuned so that the real part of the impedance of the antenna is maximized, and a plate for optimizing the reactive part of the impedance of the antenna. The impedance of the antenna is directly matched to at least one of an impedance of the transmitter and an impedance of the receiver.Type: ApplicationFiled: December 5, 2008Publication date: September 17, 2009Applicant: AMI SEMICONDUCTOR, INC.Inventors: George Shaker, Mohammad-Reza Nezhad-Ahmadi, Safieddin Safavi-Naeini, Gareth Pryce Weale
