Abstract
A wrist-mounted-type portable radio apparatus includes a main body having a front surface that faces away from the user's wrist, a rear surface that faces the user's wrist when mounted around the user's wrist, a circuit board having electrical circuitry and arranged in the main body, and wrist bands connected to the main body for mounting the device around the user's wrist. The radio apparatus also includes an antenna assembly fixed in the main body and the wrist bands, and arranged in the main body so that it is positioned on a side of the circuit board facing the front surface of the main body. Because the circuit board is not disposed on the front surface side of the antenna assembly, a radiation wave generated by the antenna assembly is not disturbed. Therefore, the wrist-mounted-type antenna device has high directivity and sensitivity.
