A decoupling structure among multi-input-multi-output antennas comprises a
dielectric substrate and a patch, wherein the patch is arranged on the
dielectric substrate and comprises an enclosed rectangular ring, a swastika-shaped structure and / or inverse swastika-shaped structure and a U-shaped strip
line structure, wherein the enclosed rectangular ring is arranged on the
dielectric substrate, theswastika-shaped structure and / or inverse swastika-shaped structure is embedded into the rectangular ring, the rectangular ring is connected with one end of the U-shaped strip
line structure, and the swastika-shaped structure and / or inverse swastika-shaped structure is embedded into a gap of the U-shaped strip
line structure. With the adoption of a mode that an inner structure and an outer structure are embedded, resonant property with
high impedance characteristic is formed, the decoupling structure is simple and integrates with the multi-input-multi-output antennas, and the whole profile of the decoupling structure is relatively low; the structure is reasonable in
layout, the space resource is reasonably utilized,
integrated design of a
wireless communication
system terminal is easy to achieve, and installation and debugging are facilitated; and the structure has relatively small size and is easy to integrate with mobile
terminal equipment, the resonant frequency can be conveniently adjusted very well, and the effect of preventing required interference is achieved.
