Abstract

An antenna (20) for a wireless device may be kept dynamically tuned to a desired center frequency to compensate for detuning which may be caused by environmental influences. A sensor (38) provides a feedback signal to a controller (34) to select an appropriate capacitance value from a variable capacitor (30, 32) to tune the antenna for the wireless device. The variable capacitor (30, 32) may comprise a plurality of fixed capacitors (50, 52, 54, 56, 58) and MEMS switches ( 60, 62, 64, 66, 68) arranged in parallel or may comprise a variable MEMS capacitor having a fixed lower plate (72) and a flexible upper plate (74).
