Radio communication apparatus and current reducing method
First Claim
1. A radio communication apparatus comprising:
- a first casing mechanically connected to a second casing in a slidable manner so that the casings may be moved between open and closed positions;
a connection section electrically connecting electronic components of the first casing to electronic components of the second casing;
an antenna device that operates at a predetermined communication frequency located in at least one of the casings;
the connection section having first and second conductors which are spaced apart and face one another when the casings are in the open position so as to form a metamaterial that resonates at the predetermined communication frequency and thus the first and second conductors are electrically connected to each other at the predetermined communication frequency,wherein the connection section is a flexible interconnect substrate including an interconnect layer, a conductor layer, and a conductor component connected to the interconnect layer;
wherein when the casings are in the closed position, the first flexible;
interconnect substrate is folded and the first conductor formed with the conductor component in one region faces the second conductor formed with a conductor layer in another region, and the flexible interconnect substrate is further extended in the open position than it is in the closed position;
wherein the flexible interconnect substrate further includes a reflection structure that reflects an electromagnetic wave of the communication frequency of the radio communication apparatus;
wherein the reflection structure is either disposed in the same layer as a second conductor layer formed on a side of a rear surface of the conductor layer with the interconnect layer interposed therebetween or is laminated on the side of the rear surface further from the second conductor layer.

Abstract
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.
