An object of the invention is to provide a folding-type portable wireless equipment which can obtain good antenna characteristics in each of opened and closed states with a simple configuration without spoiling miniaturization. A folding-type portable wireless equipment () having a first case () and a second case () includes a first circuit board () disposed at the first case (), a second circuit board () disposed at the second case (), a bendable coupling portion () which mechanically couples the first case () and the second case (), a flexible coupling element () which electrically couples the first circuit board () and the second circuit board (), a radio circuit portion () provided at the second circuit board (), an antenna element () coupled to the radio circuit portion () via a feeder line (), and a switching portion () which selectively connects and disconnects between the first circuit board () and the antenna element () in accordance with an opened/closed state of the folding-type portable wireless equipment (), wherein the antenna element () and the feeder lineare dispose at positions almost along the coupling portion ().

Folding portable wireless apparatus

In a folding mobile radio device, a gain is lowered considerably in its close state under such a condition that an upper case is excited directly in its open state to aim at a wide band and a high gain is used as an antenna. A folding mobile radio device includes a first case, a second case, a jointing portion for connecting the first case and the second case to open/close, a conductor element arranged in the first case, and a feeding element arranged in the second case. Then, in an open state via the jointing portion, the conductor element and the feeding element come close to each other and are coupled magnetically at a time of feeding a power whereas, in a close state via the jointing portion, the conductor element and the feeding element are apart from each other rather than the open state and are not coupled magnetically at a time of feeding a power.

Folding type portable wireless unit

Regardless of a user's hand holding condition, it is possible to obtain excellent antenna performance in both of folded and unfolded calling conditions. A folder type mobile radio apparatus includes an upper casehaving a first antenna element made of a metal plate, a lower casehaving a second antenna element made of a circuit board, a hinge portionpivotably connecting the upper and lower casesand, a first circuit boardhaving a ground pattern provided in an end side near the hinge portionin the lower case, an antenna switching unitfor selecting one of a first feed means for feeding the first antenna element for the radio circuiton the first circuit boardor a second feed means for feeding the second antenna element.

Foldable portable radio device

The invention is to improve antenna performance in an internal antenna in a closed state without deteriorating the antenna performance in a state where a foldable portable radio apparatus is opened. A foldable portable radio apparatus includes a foldable mechanism in which an upper casingand a lower casingare rotatably connected, a first conductor plateand a second conductor platethat are provided in the upper casing, and a feeding system that is provided in the lower casing, and connects an antenna element, a circuit board, the first conductor plate, and the circuit board, a detecting unitthat detects opened and closed states between the upper casingand the lower casing, and a first switching unitthat switches between an electrically opened state and an electrically short-circuited state between the first conductor plate and the second conductor plate according to the detected result by the detecting unit
