Antenna system and mobile terminal

Abstract

The invention relates to the technical field of the communication, and discloses an antenna system and a mobile terminal. The antenna system comprises at least one antenna group. Each antenna group comprises a first antenna and a second antenna. The first antenna is formed on a metal frame, and comprises a first gap installed on the metal frame and a second gap communicated with the first gap. Thefirst gap is extended along a circumferential direction of the metal frame, and the second gap is extended along a direction perpendicular to the first gap, so that the metal frame positioned at theedge of the first gap is divided to a first branch and a second branch. The second antenna is formed on a metallized pattern layer alternately installed with the metal frame. The metallized pattern layer is positioned in a space, away from one side of the metal frame, of a circuit board. In the antenna system, the mobile terminal is additionally provided with at least one antenna group on the original basis, the mobile terminal can be guaranteed to satisfy the mobile communication requirements of 5G and the data transmission requirements, and the good isolation and correlation of the antenna are guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to an antenna system and a mobile terminal. Background technique [0002] With the continuous development of communication technology, the fifth-generation mobile communication technology (Fifth-Generation, referred to as "5G") can be seen behind the cool hot technologies such as virtual reality, drones, and autonomous driving. The fifth-generation mobile communication technology is an extension after 4G. It is under research. The theoretical downlink speed of the 5G network is 10Gb / s (equivalent to a download speed of 1.25GB / s). In terms of capacity, 5G communication technology will be faster than 4G. Area mobile data traffic increases by 1,000 times; in terms of transmission rate, the data rate of typical users increases by 10 to 100 times, and the peak transmission rate can reach 10Gbps (4G is 100Mbps). It can be seen that 5G will surpass 4G i...

Problems solved by technology

For full-screen communication equipment, how to layout to meet the data transmission requirements and transmission capacity of 5G, and the traditional antenna layout space is already very tight, it is difficult to design more antennas with more frequency bands on this basis, and in The layout of multi-band antennas also needs to consider the requirements of isolation and correlation between antennas, which further increases the difficulty of design.
