Abstract
Systems and techniques for management of an antenna tuning frequency range. Frequency coverage needed for an antenna used in a portable communications device in a wireless communication network is determined based on communication protocols being used, with an active tuner being connected to a passively tuned antenna when a different frequency range is called for and with the active tuner being effectively isolated when only the range provided by the passively tuned antenna is needed to reduce the risk of RF mixing or intermodulation.
