Abstract

The invention discloses a mobile communication device, which is provided with a medium substrate and an antenna. The medium substrate is provided with a ground plane, a first ground plane-free interval and a second ground plane-free interval. The ground plane comprises a master ground plane and a raised ground plane. The raised ground plane is electrically connected with the master ground plane, and is extended between the first and second ground plane-free intervals to separate the first and second ground plane-free intervals. One edge in the raised ground plane is aligned with one edge in the medium substrate. The antenna has a plane structure, and is positioned on the medium substrate and provided with a feed-in part and a radiation part. The feed-in part is positioned at the first ground plane-free interval. The radiation part strides the raised ground plane. One end of the radiation part is positioned at the first ground plane-free interval, and is electrically connected to the ground plane, and the other end of the radiation part is positioned at the second ground plane-free interval, and is electrically connected to the ground plane. A coupling space in the first ground plane-free interval is reserved between the radiation part and the feed-in part. By the coupling space, the radiation part is excited by a capacitor of the feed-in part in a coupling way. The mobile communication device increases the degree of designing freedom.

Description

technical field [0001] The invention relates to a mobile communication device, in particular to a mobile communication device whose built-in antenna is integrated with a ground plane of a configurable data transmission component. Background technique [0002] With the rapid evolution of wireless communication technology, the vigorous development of the wireless communication industry has been driven, making the mobile communication device light, thin, short, small and the integration of multi-band operation become very important design goals. In the mobile communication device, in order to obtain the reduced size of the antenna while obtaining broadband operation, the known technology is to directly arrange the antenna radiator in the non-ground plane area of ​​the system circuit board in the mobile communication device to reduce the Q of the antenna. value, providing sufficient working bandwidth to cover broadband work of a wireless wide area network (WWAN, wireless wide ar...
