<p>In a folding type portable wireless unit, gain deteriorates sharply upon closure, in the case where an upper case is oscillated directly at the time of opening and used as an antenna in order to attain a wide band and a high gain. The folding type portable wireless unit comprises a first case, a second case, a coupling part for coupling the first and second cases to be opened/closed, a conductor element arranged in the first case, and a power supply element arranged in the second case. In the open state brought by the coupling part, the conductor element and the power supply element approach closely to each other and can be coupled electromagnetically at the time of power supply. In the closed state brought by the coupling part, the conductor element and the power supply element separate from each other as compared with the open state and they are not coupled electromagnetically at the time of power supply.</p> |
