Problems solved by technology

This limits the distance between the antennas that cannot be placed ideally, thus, it is inevitable that multiple antennas will interfere with each other
The main reason for interference is that each antenna is connected to the common ground of the PCB board. When two adjacent antennas receive signals, a strong coupling current will be formed between the feeds of the two antennas, which leads to Mutual interference occurs between two adjacent antennas

Abstract

The invention discloses a multi-antenna terminal, which includes a PCB board, a first antenna, a second antenna, an inductance element, a first split resonant ring group and a second split resonant ring group, the first antenna and the second split resonant ring group The two antennas are respectively connected to the ground wires on the PCB board, and the first split resonant ring group and the second split resonant ring group are arranged between the first antenna and the second antenna; the first split resonator ring The group and the second split resonant ring group are set in parallel and are respectively connected to the ground wire of the PCB board; one end of the inductance element is connected to the first split resonant ring group, and the other end is connected to the second split resonant ring group connect. The present invention can solve the problem of mutual signal interference between antennas on the multi-antenna terminal in the prior art, thereby making it more convenient for people to use, and the present invention also has the advantages of simple structure and low cost.

Description

technical field [0001] The present invention relates to the technical field of multi-antenna terminals, in particular to a multi-antenna terminal. Background technique [0002] Multiple Input Multiple Output (MIMO) or Multiple Transmit Multiple Receive antenna technology is a major breakthrough in antenna technology in the field of wireless mobile communications. This technology can double the capacity and spectrum utilization of the communication system without increasing the bandwidth, and is a key technology that must be adopted by the new generation of mobile communication systems. MIMO technology allows multiple antennas to simultaneously transmit and receive multiple spatial streams (frequency bands) and is able to distinguish signals to or from different spatial orientations. The application of the multi-antenna system enables parallel data streams to be transmitted simultaneously. At the same time, using multiple antennas at the sending end or receiving end can sig...
