Description

Mobile terminal

Technical Field

The invention relates to the technical field of electronic products, in particular to a mobile terminal.

Background

The fifth Generation mobile communication technology (5th-Generation, 5G) can provide higher communication speed, lower latency, and a larger number of simultaneous connections than the previous Generation technologies. Because the frequency is low and does not cause great space propagation loss, the communication technology with the frequency band below 6GHz (Sub-6GHz) is one of the key technologies in the 5G technology. Therefore, mobile terminals equipped with 5G Sub-6GHz antennas will be increasing in the future.

Most of the current 5G Sub-6GHz antennas are designed to be the same as other fourth generation mobile communication technology (4G) and wireless internet access (Wifi) antennas, and are distributed around the inside of the mobile terminal, such as a middle frame. The 4x4 Multiple-Input Multiple-Output (MIMO) technology required by the 5G Sub-6GHz technology requires 4 antennas per frequency band, which makes the space required by the antennas larger and larger, and makes it more and more difficult for the internal space of the mobile terminal to meet the antenna requirements. Thus, when the 5G Sub-6GHz antenna is designed, a part of the antenna may occupy the space of other devices, and the function of the occupied part of the devices is lost. Or, the antennas in some frequency bands are used together with antennas in other frequency bands, which needs to be implemented by adding a combiner, but adding a combiner device may cause insertion loss, resulting in a decrease in the efficiency of the radio frequency path.
