Abstract

A foldable portable wireless communication device, which can ensure the miniaturization of the shell and good antenna characteristics, it has: a first shell, including a microphone and / or an operating part; a second shell, including a receiver and / or a display part , and is rotatably linked with the first casing by a hinge part, and the hinge part is arranged on one end portion of the first casing and is located on the front side thereof. An antenna board is arranged in a region in the first casing, which is behind the hinge part; a circuit board on which the radio frequency circuit part is mounted is arranged in the first casing without being connected to the hinge part. in the overlapping area. By setting the extension direction of the connection conductor along the longitudinal direction of the first housing near the high-frequency wave input / output point, the connection conductor is configured as a monopole antenna so that the connection conductor connects the antenna board and the radio frequency circuit The high-frequency wave input / output points of the components are connected.

Description

field of invention [0001] The invention relates to a foldable portable wireless communication device, in particular to a foldable portable wireless communication device with a built-in antenna. technical background [0002] Cellular phones are becoming very popular as foldable portable wireless communication devices. There are some such cellular telephones that incorporate the antenna into a housing, ie, they have a built-in antenna. [0003] For example, in a foldable cellular phone disclosed in Unexamined Japanese Patent Application KOKAI Publication No. 2004-297535, an operation-side housing on which a microphone, a key operation member, etc. are disposed extends upward beyond a hinge member that Provided on an end portion of the front surface of the housing. This foldable cellular phone adopts a structure in which the antenna is accommodated in a region extending from below the hinge member to the extended portion of the operation side case. [0004] Since the foldabl...
