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.
