Abstract

The invention provides a multifrequency terminal antenna used for a full-metal housing, and belongs to the technical field of an antenna. The antenna comprises a metal housing arranged on the back surface of a system circuit board, a feed network and gaps arranged on the front surface of the system circuit board. The metal housing is on the back surface of the system circuit board, and the metal housing is provided with a double-end opening gap and a single-end opening gap. Feed branches matched with feed ports in the feed network respectively cross the above two gaps. Stimulation gaps form multi-frequency-point resonance. Through improvement that a U-shaped folded metal sheet loading on the double-end opening gap, a three-dimensional structure which is different from an existing two-dimensional slot antenna is formed, used to cover more frequency bands. The antenna solves problems that performance of the antenna is damaged caused by coexistence of the antenna and the large-area metal housing, and improves intensity, texture, and aesthetic perception of a terminal device.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a multi-frequency terminal antenna used in an all-metal casing. Background technique [0002] With the advent of the information age, mobile communication has achieved unprecedented development. As an important part of wireless communication, the antenna determines the electrical performance of the terminal equipment to communicate with the outside world. Generally speaking, a good antenna should significantly improve the overall performance of the terminal equipment while effectively reducing the space occupied by the antenna, and increase the The signal strength obtained by the end device and the rate of data communication. Facing the development of mobile communication networks, 4G communication networks that support high-speed data transmission are currently being popularized, and the research on 5G communication networks, which is an upgraded version of 4G comm...
