Patent ID: 8489109

Claim:
A portable wireless device comprising: a body; a first communication unit arranged in the body and including a first antenna unit that communicates with an external device by way of a first usable frequency band, and a first information processing unit that performs predetermined processing with respect to information communicated by the first antenna unit; a second communication unit arranged in the body and including a second antenna unit that is disposed in the vicinity of the first antenna unit and communicates by way of a second usable frequency band that is a frequency band overlapping a high-order secondary resonance point of the first usable frequency band, and a second information processing unit that performs predetermined processing with respect to information communicated by the second antenna unit; an adjustment unit which adjusts a resonance point of the first usable frequency band of the first antenna unit; and a control unit which adjusts by the adjustment unit the resonance point of the first usable frequency band so that a high-order secondary resonance point of the first usable frequency band does not overlap with the second usable frequency band, wherein the first antenna is a loop antenna comprising a wiring pattern, the adjustment unit is added to the wiring pattern of the loop antenna, and the control unit adjusts the resonance point of the first usable frequency band by switching a first pathway in which the adjustment unit is connected to the wiring pattern and a second pathway in which the adjustment unit is not connected to the wiring pattern.
