Multi-antenna layout structure of antenna bracket and mobile terminal

Abstract

The invention relates to the technical field of antennas, and discloses a multi-antenna layout structure of an antenna bracket, and a mobile terminal. According to the multi-antenna layout structure,a plurality of feed branches arranged at intervals are coupled around a common coupling branch on an antenna bracket, one feed branch is provided with at least one feed end, the feed end is used for being electrically connected with a radio frequency port of a mobile terminal, and a 1 / 4 wavelength impedance converter is also electrically connected between the two feed ends electrically connected with the two radio frequency ports in the same frequency band. According to the invention, a plurality of feed branches are coupled at the same time through a common coupling branch, so that multi-antenna layout is realized in a limited space; and two radio frequency ports in the same frequency band are connected with corresponding feed ends through a 1 / 4 wavelength impedance converter to form an isolation network, so that mutual interference between two radio frequency ports working in the same frequency band can be greatly reduced, and the isolation requirement between antennas is met.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a multi-antenna layout structure of an antenna bracket and a mobile terminal. Background technique [0002] With the development of wireless communication technology, the transmission methods of mobile terminals are becoming more and more abundant, and the number of antennas required is also increasing. In the prior art, the antennas are independent of each other, and each antenna needs to occupy a separate block. In the wiring area, especially with the development of 5G technology, there is more demand for antennas, and due to the limited installation space inside the mobile terminal, there are fewer and fewer locations for antennas to choose, and the increase in the number of antennas also leads to the gap between antennas. The distance is shorter, so that the mutual influence between antennas is becoming more and more serious; [0003] Therefore, how to implement multi-anten...
