Abstract:
1. A portable communication apparatus, comprising: a circuit board disposed in the apparatus; an antenna disposed on the circuit board; a battery pack installed on an installation section of the apparatus; a battery can included within the battery pack; a plurality of ground terminals connected to a ground layer of the circuit board; a pair of a first conductive surface and a second conductive surface formed on a circumferential surface of the battery pack, each having an elongated shape so as to be arranged side by side in parallel on a same plane along two edges facing each other; and a plurality of individual capacitors arranged along a longitudinal direction of the first conductive surface and the second conductive surface, respectively, and being respectively connected between the battery can and the first conductive surface and the second conductive surface through which high frequency current runs, respectively, wherein, on an inner surface of the installation section of the apparatus, a plurality of ground terminals are disposed so as to be pushed to the first and second conductive surfaces, and upon the battery pack being installed in the installation section, conduction is established between the first and second conductive surfaces and the ground terminals, and the longitudinal direction of the first and second conductive surfaces is arranged to intersect with a direction in which a high-frequency current propagates from an antenna side to form an electromagnetic shielding structure.
