摘要： A multi-resonant antenna device includes an antenna element and an LC parallel resonance circuit making the antenna element resonate in a plurality of frequency bands, and the LC parallel resonance circuit includes a T-type circuit or PI-type circuit including an inductance element, acting as a shunt element, and capacitance elements, which prevent the impedance from becoming infinite in a certain frequency band. In this way, a drop, that is, a notch portion, in the frequency characteristic causing deterioration of the gain can be eliminated.

摘要： A mobile telephone device includes a display casing having display panels and a television antenna unit, an operation casing having an operation unit and a mobile telephone device antenna unit, and a hinge unit for rotatably connecting the display casing to the operation casing. The television antenna unit is provided at the end of the display casing opposite the end having the hinge unit. The mobile telephone device antenna unit is provided at the end of the operation casing on the hinge unit side. Therefore, the antennas are always separated by the length of the display casing. In addition, a ground electrode is formed so as to continuously extend on the display casing and the operation casing. One end of the television antenna unit electrically communicates with this ground electrode. Thus, a ground electrode having a length corresponding to the television antenna unit can be provided.
