Abstract
A mobile wireless device enables effective use of space in a case while reducing degradation of ah antenna gain and maintaining communication quality even if a plurality of antennas having different frequency bands are arranged close to one another. A magnetic antenna has a first switch unit, a second switch unit, and a concentrated constant circuit which are added to a wiring pattern at the side near to a main antenna, so that a first path and a second path can be selected. Under a predetermined condition, a CPU controls the first switch and the second switch to electrically connect a terminal (A1) to a terminal (B1) and electrically connect terminal (A2) to terminal (B2), thereby forming the first path; and electrically connect terminal (A1) to a terminal (C1) and electrically connect terminal (A2) to a terminal (C2), thereby forming the second path connected via the concentrated constant circuit.

14. 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. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
