Abstract

Methods and systems for measuring and optimizing integrated antenna performance are disclosed and may include transmitting FM signals over a range of frequencies utilizing one or more antenna configurations. The FM transmitter may be calibrated based on a signal received by one of a plurality of wireless protocol receivers in the wireless device. The wireless device may include one or more other corresponding transmitters that utilize other wireless protocols. The transmitted FM signals may be received by a test set, which may then transmit a signal utilizing a different wireless protocol for adjusting the FM transmitter. The frequency of the transmitted FM signals may be varied utilizing a tunable oscillator, and the antenna configurations may be adjusted accordingly by impedance matching them to the FM transmitter. The FM transmitter and FM receiver and the tunable oscillator may be integrated within a single chip.
