Communication terminal
First Claim
1. A communication terminal, comprising:
- a hinge portion, which connects two casing members having conductive portions so as to freely open and close; and
an antenna, which is provided near the hinge portion in one casing member of the two casing members;
wherein the hinge portion includes;
a first rotating member, which is formed by conductive material and which serves as an axis for rotating the two casing members in an opposed direction of the two casing members; and
a second rotating member, which is formed by the conductive material and which serves as an axis for rotating one casing member of the two casing members relative to the other casing member under a non-opposed state of the two casing members in a direction perpendicular to a rotating direction while the first rotating member serves as the axis;
wherein a predetermined interval for capacity coupling of the conductive portions of the two casing members is set; and
wherein the hinge portion is insulated from one of the conductive portions of the two casing members.

Abstract
The invention aims at providing a communication terminal capable of suppressing degradation of an antenna gain irrespective of whether the casing of the communication terminal is opened or closed. The communication terminal includes a hinge for coupling in a foldable manner a first casing member and a second casing member, each including conductors such as a first printed board and a second printed board. In close proximity to the hinge in the second casing member is provides a second antenna. The hinge includes a first rotation axis composed of a conductive metal material working as an axis of rotation of two casing members in opposite directions and a second rotation axis composed of a conductive metal material working as an axis of rotation in a direction orthogonal to the direction of rotation about the first rotation axis. A predetermined clearance L to place the conductors of the first and second casing members in capacity coupling is formed and the hinge is insulated from the conductor of one of the two casing members.
