A radio communication apparatus includes: a first casing; a second casing; a connection section that connects the first and second casings to each other to be movable; and an antenna device that operates at a predetermined communication frequency. In the radio communication apparatus, first and second states are switched between by relatively moving the first and second casings. The first state is a state in which the first and second casings are opened or closed with respect to one another, and a first conductor (122) installed from the connection section to the first casing and a second conductor (240) installed from the connection section to the second casing are separated and faced each other. In the first state, the first conductor (122) and the second conductor (240) are electrically connected to each other at the communication frequency. The second state is a state in which the first and second casings are closed or opened with respect to one another.

The fourth conductor (300) is opposite to the second conductor (200), and thus forms a transmission line using the second conductor (200) as a return path.

摘要:
A wireless communication device (100) includes a first casing (10) and a second casing (20), and is switched between at least a first state and a second state by displacement of the first casing (10) and the second casing (20). The first casing (10) includes a first conductor (15) and a conductor element (36a) connected thereto. The second casing (20) includes a second conductor (25), and is connected to the first casing (10) so as to be rotationally displaceable with respect to each other around a perpendicular axis. In a first state, an opposite region (241) in the second conductor (25) and the conductor element (36a) are located at positions opposite to each other, and the conductor element (36a) and the second conductor (25) allow electrical conduction to each other at a predetermined frequency. In a second state, the electrical conduction state is different from that in the first state.
