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. The method for antenna design includes providing estimate of a package, designing possible realization(s) of the antenna given the space limitations of the package to realize maximum power transfer around the head, for a given design of LNA and PA, generating power efficiency maps for all possible bias realizations versus all possible impedance values of the antenna, and modifying the antenna design in order to maximize the overall link efficiency.
