Abstract: Embodiments of the present invention provide a decoupling assembly, a multiple-antenna system, and a terminal, and relate to the field of communications technologies, to change a radiation direction of an electromagnetic wave, thereby achieving a decoupling effect in a relatively large frequency range. The multiple-antenna system includes a first antenna unit and a second antenna unit that are adjacent to each other. A decoupling assembly is disposed between the first antenna unit and the second antenna unit, and the decoupling assembly is made of an electromagnetic material with electrical anisotropy or electromagnetic bianisotropy, to reduce a coupling generated between the first antenna unit and the second antenna unit.

Abstract: This application discloses an antenna system, includes: a ground plate, at least one antenna pair disposed on the ground plate, and a decoupling assembly disposed on a radiation surface of the antenna pair; where the antenna pair includes a first antenna and a second antenna; the decoupling assembly is configured to adjust antenna radiation directions of the first antenna and the second antenna. In this application, the following problem is resolved: A poor effect is achieved when coupling between antennas is reduced by using a slit because there are many electronic elements in a mobile terminal and the slit is easily affected by surrounding electronic elements. Antenna radiation directions of the antennas are changed by using the decoupling assembly disposed on the radiation surface of the antenna pair, thereby improving isolation between the antennas and antenna radiation efficiency.
