摘要： A mobile phone unit is provided in which a characteristic of an antenna is improved and SAR is reduced without lowering an antenna gain during communication. An antenna 26 (electrical length λ/4), an antenna connection conductive member 22 (electrical length λ/4) that is a circuit board connected to the antenna 26, an opposite side conductive member 42 that is a circuit board opposed to the antenna connection conductive member 22, and an electric connection portion 24 that electrically connects an edge portion 222, which is on the opposite side to the antenna 26, of the antenna connection conductive member 22 and an opposite side edge portion 422, which is opposed to the edge portion 222, of the opposite side conductive member 42 (electrical length λ/4) are included. A gain on the opposite side to an LCD side casing 4 becomes large when seen from the antenna 26, and the electric currents are counteracted to be small and consequently a gain becomes small on the side of the LCD side casing 4.

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.
