Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. It should be understood that the specific embodiments described here are only used to explain the related application, not to limit the application. It should also be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings.

[0035] Antenna is an indispensable key component of wireless communication equipment. As a transducer, the antenna can radiate the guided wave in the waveguide into space, and can also convert the electromagnetic wave in space into the guided wave in the waveguide. The performance of the antenna directly affects the quality of communication. With the development of science and technology and the improvement of integration level, the size of wireless terminals is constantly shrinking. ...

Abstract

The embodiment of the invention discloses an antenna system and a terminal. The antenna system comprises a bracket, a metal sheet, a grounding plane and a feed transmission line, wherein the bracket is parallel to the grounding plane, the grounding plane is located below the bracket, the metal sheet is arranged on the upper surface of the bracket and is parallel to the grounding plane, the metal sheet is provided with a gap to form an open gap antenna, the feed transmission line is arranged on the lower surface of the bracket, and the open gap antenna is coupled and fed through the feed transmission line so as to excite multiple different antenna modes, so that multiple different frequency band ranges are covered.

Description

technical field [0001] The embodiments of the present application relate to the technical field of antennas, and in particular, to an antenna system and a terminal. Background technique [0002] With the continuous development of terminal technology, the whole machine tends to become thinner and lighter. Therefore, a full screen or curved screen terminal with a higher screen-to-body ratio emerges as the times require. However, the industrial design (Industrial Design, ID) requirement of a terminal with a high screen-to-body ratio will affect the configuration of other components in the terminal, including the antenna, which is an important component for sending and receiving signals. [0003] At the same time, with the determination of the communication frequency band of the fifth generation mobile communication technology (5th generation mobile networks, 5G), the number of antennas in the terminal is also more than that of the long term evolution (Long Term Evolution, LTE)....
