Abstract
Devices and methods for dynamically selecting a matching network for an antenna are provided. In one example, an electronic device capable of selecting such a matching network may include an antenna, several selectable matching networks, a radio receiver, and matching network control circuitry. The radio receiver may couple to the antenna via one of the selectable matching networks to receive a radio signal with both an analog and digital component. The matching network control circuitry may select the matching network from among the several selectable matching networks based at least in part on a characteristic of the digital component of the radio signal.
