  • Publication number: 20070229383
    Abstract: By devising the case shape and antenna placement, it is possible to provide a mobile radio terminal capable of always having a high antenna sensitivity even when the mobile radio terminal is placed in a pocket of user's clothes. In this mobile radio terminal (1), the case (2) has a plane A having a flat shape and a plane B having a protruding portion (2a) at a part of the center portion or the entire portion. An antenna element (3) is placed on the protruding portion (2a) of the plane B in parallel to the plane A. Since the plane B has a protrusion or a curved shape, when the user puts the terminal into the pocket of his/her clothes, he/she unconsciously puts the terminal with the plane A in contact with his/her body side. Accordingly, the mobile radio terminal (1) is always contained in the clothes pocket with the antenna element (3) positioned at a distance from the user's body, i.e., at the farthest position from the user's body.
