Embodiment Construction

[0068] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0069] For the convenience of understanding, the terms involved in the embodiments of the present invention are explained below.

[0070] Anisotropy: Refers to the fact that the values ​​of the constitutive parameters of a substance propagating an electromagnetic field are different in each direction. Specifically, anisotropy can include electrical anisotropy (the components of the dielectric constant are different in each direction), magnetic anisotropy (the components of the magnetic permeability are different in each direction) and double anisotropy (the components of the dielectric constant are different in each direction). and permeability components are different in each direction). It should be noted that the "different compone...

Abstract

The invention discloses an antenna system and belongs to the field of antennas. The antenna system comprises a grounding plate, at least one group of antenna pairs arranged on the grounding plate, anda decoupling assembly arranged on the radiating surfaces of the antenna pairs, wherein each antenna pair comprises a first antenna and a second antenna; the decoupling assembly has electric anisotropy and the electric anisotropy means that components of equivalent dielectric constants of the decoupling assembly in various directions are different; and the decoupling assembly is used for adjustingthe antenna radiation directions of the first antennas and the second antennas, wherein the isolation of the first antennas and the second antennas after adjustment is greater than that of the firstantennas and the second antennas before adjustment. According to the antenna system, the problem that the effect of reducing coupling between the antennas by using slots is poor due to the fact that amobile terminal comprises a plurality of electronic components and the slots are easily affected by peripheral electronic components is solved; and the effect of improving the isolation between the antennas and the antenna radiation efficiency is achieved through changing the antenna radiation directions of the antennas by using the decoupling assembly arranged on the radiating surfaces of the antenna pairs is achieved.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an antenna system. Background technique [0002] Multiple-Input Multiple-Output (English: Multiple-Input Multiple-Output; MIMO for short) antenna technology is one of the core technologies in the field of wireless communication, and is used to improve the signal throughput rate of terminals. [0003] A terminal using MIMO antenna technology receives signals through multiple receiving antennas and transmits signals through multiple transmitting antennas, so as to improve the signal throughput rate of the terminal without increasing spectrum resources and antenna transmission power. When MIMO antenna technology is applied to mobile terminals such as smartphones and tablet computers, due to the size limitation of mobile terminals, multiple antennas are concentrated in a small area, resulting in strong coupling between antennas, affecting The transmit efficiency of the antenna.
