<p>A mobile wireless communication device is provided for making it possible to set a small multiband antenna to which a plurality of different frequencies can be applied by disposing an antenna element in an input unit with easily securing an upper space. An antenna element (12) is disposed in zigzag around each input key of a dial unit (13) and is supplied with electric power at point A from an electric power supply unit (11) while being supplied with electric power at point B from an electric power supply unit (14). In this mobile wireless communication device, since the antenna element (12) is disposed and mounted on a lattice structure portion of the dial unit (13) and a path length (A-B, B-C or A-B-C) of the power supply point (A or B) or the antenna element (12) is changed in accordance with a desired frequency, the free changeover of the antenna element (12) can comply with multiband requirements so that an antenna to adapt to environment conditions can be achieved. Further, it is relatively easy to secure a space in the dial unit (13), and the antenna element (12) can achieve the defining of a saved space by making use of the dial unit (13).</p> |
