Antenna system and mobile terminal

Abstract

The embodiments of the invention relate to the communication field and disclose an antenna system and a mobile terminal. The antenna system is applied to the mobile terminal. The antenna system comprises a first feeding point arranged on a circuit board, a first millimeter wave array antenna electrically connected to the first feeding point, a second feeding point, a second millimeter wave array antenna electrically connected to the second feeding point, a third feeding point, a third millimeter wave array antenna electrically connected to the third feeding point, a fourth feeding point and afourth millimeter wave array antenna electrically connected to the fourth feeding point. The wave beam of the first millimeter wave array antenna covers a space where Z is greater than 0. The wave beam of the second millimeter wave array antenna covers a space where the Z is less than 0. The wave beam of the third millimeter wave array antenna covers a space where Y is greater than 0. The wave beam of the fourth millimeter wave array antenna covers a space where the Y is less than 0. In the invention, the wave beam covering range of the antenna system to the spaces surrounding the mobile terminal is increased so that the space radiation covering rate of the antenna system is improved and a capability for the mobile terminal to receive signals is enhanced.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, 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 in all aspects ...
