Abstract: An antenna arrangement includes a switch having an open state and a closed state, a first antenna that operates as a first active driven element in a first frequency band in response to the switch being in the open state, and a second antenna that operates as a second active driven element in a first frequency band in response to the switch being in the open state. The closed state configures the first antenna and the second antenna to operate in a second frequency band different from the first frequency band by operatively coupling a first impedance between the first antenna and a radio frequency ground, and by operatively coupling a second impedance between the second antenna and the radio frequency ground. The first antenna functions as a parasitic element in the second frequency band and the second antenna functions as an active driven element in the second frequency band.

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.
