Patent ID: 7839340

Claim:
A foldable mobile wireless apparatus having an upper case and a lower case, said upper case and lower case being connected by a hinge member and able to be opened and closed, the foldable mobile wireless apparatus comprising: a flat conductor that is provided in the upper case; a hinge section that has conductivity and is electrically connected to the flat conductor; a circuit board that is provided in the lower case; a first feeding section and a second feeding section that are provided and spaced by a predetermined distance in a width direction in the hinge section, and that supply power from the circuit board to the flat conductor via the hinge section; a harmonic signal distributing section that is provided on the circuit board and distributes a harmonic signal to the first feeding section and the second feeding section; a harmonic signal supplying section that supplies the harmonic signal to the harmonic signal distributing section; a phase setting section that sets an excitation phase of the harmonic signal at the second feeding section to a different value from an excitation phase of the harmonic signal at the first feeding section; a phase difference controlling section that controls the phase difference between the excitation phase of the harmonic signal at the first feeding section and the excitation phase of the harmonic signal at the second feeding section; and an inclination angle detection section that detects an inclination angle of the foldable mobile wireless apparatus and generates a value of the detected inclination angle, wherein: the phase difference controlling section controls the phase difference by switching between a phased power supply and an in-phase power supply in accordance with a GPS reception mode for a GPS receiving function and a mail transmission-reception mode which is one function of the mobile wireless apparatus, and controls the phase difference in accordance with the value of the inclination angle detected by the inclination angle detection section.
