Abstract: 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 6 detects open/close of bodies 1 and 2. When the bodies 1 and 2 are open, a first antenna 4 and a wireless circuit 24 are connected and resonant frequency of a second antenna 5 is adjusted into a first frequency bandwidth, and when the bodies 1 and 2 are closed, the resonant frequency of the second antenna 5 is adjusted into the first frequency bandwidth and a second frequency bandwidth and a wireless circuit 24 is connected. Therefore, when the bodies 1 and 2 are open, it is possible to reduce a local average SAR by separating an antenna current. Further, when the bodies 1 and 2 are closed, it is possible to obtain a high antenna gain.

Abstract: A portable wireless device is provided that eliminates the need for an antenna protruding from an housing by including a first housing and a second housing operating as a dipole antenna thus ensuring portability and delivering a high antenna performance despite its compact, low-profile and lightweight design. The portable wireless device according to the invention includes a first housing 1; a second housing 2; and a sliding unit 21 for slidably coupling the first housing 1 and the second housing 2 to each other; wherein the first housing 1 is arranged a predetermined spacing apart from the second housing 2 and includes a power feeding unit 7 for feeding power: between the first housing 1 and the second housing 2 and wherein the first housing 1 and the second housing 2 operate as a dipole antenna. The portable wireless device does not include an antenna protruding from an housing. This ensures portability and delivers a high antenna performance despite its compact, low-profile and lightweight design.
