Antenna system and mobile terminal

Abstract

The embodiment of the invention relates to the field of communication, and discloses an antenna system and a mobile terminal. The antenna system is applied to the mobile terminal. The antenna system comprises a first feeding point which is arranged on a circuit board, a first millimeter wave array antenna which is electrically connected to the first feeding point, a second feeding point, a secondmillimeter wave array antenna which is electrically connected to the second feeding point, a third feeding point, a third millimeter wave array antenna which is electrically connected to the third feeding point, a fourth feeding point, and a fourth millimeter wave array antenna which is electrically connected to the fourth feeding point, wherein the beam of the first millimeter wave array antennacovers the space (X is more than 0); the beam of the second millimeter wave array antenna covers the space (X is less than 0); the beam of the third millimeter wave array antenna covers the space (Y is more than 0); the fourth millimeter wave array antenna covers the space (Y is less than 0). According to the system, the beam covering range in the surrounding space of the mobile terminal is expanded, so that the space radiation covering rate of the antenna is increased, and the capacity of receiving signals by the mobile terminal is improved.

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 ...

AI Technical Summary

Problems solved by technology

The inventors found that there are at least the following problems in the prior art: 5G terminals also need to use millimeter-wave phased array antennas, and the phased array of 5G terminals is an N×N dot matrix, but this phased array occupies a large space on the mobile phone. It is not easy to lay out, and the scanning angle setting of this phased array is complicated

Since the scanning coverage of a single phased array antenna is generally smaller than a hemisphere, if a 5G terminal uses a single phased array antenna, it may cause the problem of unstable reception of smart terminals.
