Patent ID: 8232926

Claim:
A mobile radio apparatus comprising: a first housing that comprises a display surface; a second housing that comprises an operation panel; a hinge part that joints the first housing and the second housing rotatably; a radio section that is provided in the first housing; a power feeding point that is provided in the first housing and that connects with the radio section; a first conductive part that is arranged in the first housing, and that electrically connects with the power feeding point in the vicinity of the hinge part; a second conductive part that is arranged in the second housing, that electrically connects with the power feeding point and that is combined with the first conductive part to form a first antenna with an electrical length half the wavelength; a second antenna that is arranged near the hinge part of the second housing, and that uses as a resonance frequency a second frequency which is different from a first frequency which is a resonance frequency of the first antenna; a first frequency blocking section that connects to the power feeding point, in parallel to the radio section, and that blocks the first frequency; and a terminating section that electrically terminates the second frequency which is connected to an output side of the first frequency blocking section.
