Abstract
A novel and useful adaptive antenna tuner and associated calibration mechanism for passive adaptive antenna matching networks. The tuner is suitable for use with cellular antennas and in one embodiment uses MEMS based tunable devices. The tuner contains voltage and current sensors inserted before the antenna matching network. The sensed complex impedance generates one or more update control signals for the tuning algorithm which drives the MEMS-based tunable devices.
