Abstract

Provided is a multi-antenna terminal. The multi-antenna terminal includes a Printed Circuit Board (PCB), a first antenna, a second antenna, an inductance element, a first split-ring resonator group and a second split-ring resonator group. The first antenna and the second antenna are respectively connected to a grounding wire on the PCB; the first split-ring resonator group and the second split-ring resonator group are arranged between the first antenna and the second antenna; the first split-ring resonator group and the second split-ring resonator group are arranged in parallel, and respectively connected to a grounding wire on the PCB; one end of the inductance element is connected to the first split-ring resonator group, and the other end of the inductance element is connected to the second split-ring resonator group. The multi-antenna terminal can solve the problem that signals between respective antennas on the multi-antenna terminal interfere with one another in the related art, so that the use by people is more convenient. In addition, the multi-antenna terminal has the advantages of simple structure, lower cost and the like.

First claim
