Abstract

The invention discloses a mobile terminal antenna device which comprises a metal frame arranged on a mobile communication terminal shell, a first radiating body and a second radiating body arranged on an antenna carrier and a main circuit board arranged in a mobile communication terminal, wherein a main earth point on the main circuit board is connected with the metal frame; the first radiating body is provided with a coupling gap and is connected with a radio-frequency feed source on the main circuit board via a conducting connector, and an earth point on the first radiating body is connected with the metal frame via a conducting connector; and the second radiating body as a double-grounded parasitic antenna branch of the antenna device is used for expanding low-frequency bandwidth. The mobile terminal antenna device is a coupled feed-in type monopole antenna device. Compared with the prior art, the mobile terminal antenna device has the advantages of ultralow low-frequency bandwidth, good antenna performance, high efficiency and the like, the problem that a large metal part of the mobile communication terminal and the antenna coexist is also well solved, and the metal texture of the appearance of the mobile communication terminal is better ensured on the shape.

Description

technical field [0001] The invention relates to an antenna device for a mobile communication terminal, in particular to a coupling-feeding monopole antenna device applied to a mobile phone. Background technique [0002] With the development of wireless communication technology, the requirements for wireless communication equipment are getting higher and higher. As the antenna for receiving and transmitting electromagnetic waves, there are also various structures to meet the requirements of communication equipment, and the performance or structure of the antenna has also been improved. challenge. The vigorous development of wireless communication technology has led to more and more information sub-modules on the mobile terminal system. For example, the current smart phone system is generally equipped with multiple sub-communication modules. The increase of these sub-communication modules will inevitably lead to the expansion of the antenna frequency band and the An increase...
