<p>A radio communication apparatus is provided that can be used to control an impedance between circuit boards over a wide range of frequencies and the physical volume of which is small. Housings 1 and 2 are linked via a hinge unit 3 in an openable/closeable manner, and circuit boards 4 and 5 are housed in the housings 1 and 2, respectively. The circuit boards 4 and 5 are connected via a group of circuit connecting lines 6 functioning as an inductor L1. For the hinge unit 3, one end thereof is linked to an end portion 2a of the housing 2 and the other end thereof is linked to a portion 1b located more internally than an end portion 1a of the housing 1. In a state in which the housings 1 and 2 are unfolded, a region D1 extending from the portion 1b to the end portion 1a of the housing 1 overlaps a region D2 near the end portion 2a of the housing 2 in a projection domain. A high dielectric member 7 is arranged to this overlapped region, and a capacitor C is constituted by the high dielectric member 7 and ground areas 41 and 51. As a result, the circuit boards 4 and 5 are in a state in which the circuit boards 4 and 5 are connected via a parallel circuit in which the inductor L1 and the capacitor C are connected in parallel.</p> |
