Abstract:
1. A portable wireless apparatus, in which: a first housing and a second housing are pivotably connected by a hinge portion; the first housing includes a first antenna element; the second housing includes a second antenna element, a circuit board having a gland pattern, and a second power feeding portion provided at an end of the second antenna element; and the hinge portion includes a first hinge portion and a second hinge portion that are made of an electrical conductive metal and a connecting portion that electrically connects the first hinge portion with the second hinge portion and rotatably supports the first and second hinge portions, the first hinge portion being electrically connected to the hinge portion-sided end of the first antenna element of the first housing, and the second hinge portion being disposed at a predetermined distance from the gland pattern on the circuit board of the second housing and provided with a first power feeding portion; wherein the portable wireless apparatus comprises: an antenna switching circuit that selectively connects one of the first antenna element and the second antenna element to a wireless circuit; a resonance circuit and a matching circuit that are selectively connected to the second antenna element; a switching circuit that connects the second power feeding portion with one of the resonance circuit and the matching circuit; and an open/close detecting unit that detects an open/close state of the first housing and the second housing; wherein the antenna switching circuit selects the first antenna element while the switching circuit selects the resonance circuit, in case such that the first housing and the second housing are opened; and wherein the antenna switching circuit selects the second antenna element while the switching circuit selects the matching circuit and power is supplied through the matching circuit, in case such that the first housing and the second housing are closed.
