Abstract
A method of adapting an antenna to a transceiver system having a receiver subsystem and a transmitter subsystem comprises using an automatic tuning system to tune the antenna with respect to the receiver subsystem. The tuning results in an optimal receive signal at the receiver subsystem in response to RF energy radiated to the antenna. The tuning system may include a tuning detection element for radiating RF energy to the antenna, and a tuning element for tuning the antenna. After tuning the antenna, the method further comprises tuning a tunable matching network, coupled between an output of an RF power device of the transmitter subsystem and an input of the antenna, to facilitate an optimal power transfer amount from the RF power device to the antenna while the RF power device operates according to certain desired parameters. The desired parameters may include output power and efficiency.
