Communication device and mobile terminal

Abstract

The invention provides a communication device and a mobile terminal. The communication device comprises a middle frame, an antenna support, a mainboard and an antenna assembly. The antenna support, the mainboard and the antenna assembly are arranged in the middle frame; the middle frame is provided with a breaking joint and a plurality of radiation branches; the antenna assembly comprises a feed elastic sheet and a conductive metal sheet, the feed elastic sheet is connected with the middle frame, and the conductive metal sheet is arranged on the antenna support; the mainboard is used for transmitting or receiving a radio frequency signal; the feed elastic sheet is used for exciting resonance of each radiation branch knot on the middle frame based on a radio frequency signal so as to excite each radiation branch knot to generate first resonance; the breaking joints are used for coupling the radiation branches; and each radiation branch knot is coupled with the conductive metal sheet and is used for exciting the conductive metal sheet to generate second resonance so as to increase the resonance bandwidth of the communication device. The problem that the internal space of an existing communication device is crowded can be well relieved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a communication device and a mobile terminal. Background technique [0002] With the development of communication technology and the increasing demand for communication frequency bands, in order to meet the communication frequency band requirements of communication devices such as mobile phones and tablet computers, the internal space of communication devices is increasingly crowded, so there are higher requirements for the arrangement of antennas in communication devices. However, due to the poor rationality of the antenna arrangement in the current communication equipment, the internal space of the communication equipment is relatively crowded, which in turn makes it difficult to widen the antenna frequency band and cannot adapt to the current trend of increasing frequency band demand. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the...
