摘要： An antenna device that includes an antenna having a single feed and a shunt circuit. The shunt circuit includes a first shunt matching circuit causing impedance, viewed from a main path connecting the antenna and a radio frequency circuit, to be substantially infinite with respect to all frequency ranges handled by the antenna, and a second shunt matching circuit providing a predetermined impedance characteristic with respect to a first subset of the frequency ranges handled by the antenna. Each of the first and second shunt matching circuits are selectively connected to the main path, and a selection controller of the antenna device controls selection of which of the first and second shunt matching circuits are connected to the main path.
