Portable wireless apparatus

The present invention provides a folding type and portable wireless apparatus with a built-in antenna, particularly a portable wireless apparatus that reduces a local average SAR and improves performance of antenna.A housing open/close detecting unit detects open/close of bodies and . When the bodies and are open, a first antenna and a wireless circuit are connected and resonant frequency of a second antenna is adjusted into a first frequency bandwidth, and when the bodies and are closed, the resonant frequency of the second antenna is adjusted into the first frequency bandwidth and a second frequency bandwidth and a wireless circuit is connected. Therefore, when the bodies and are open, it is possible to reduce a local average SAR by separating an antenna current. Further, when the bodies and are closed, it is possible to obtain a high antenna gain.
