The invention discloses a self-decoupling antenna array based on a dielectric resonator, the antenna array comprises a bottom layer dielectric substrate, a feed structure is installed on the lower surface of the bottom layer dielectric substrate, the upper surface of the bottom layer dielectric substrate is provided with a metal ground plane, and the metal ground plane is provided with a dielectric resonator. And a dielectric substrate on which the antenna radiation unit is located is arranged on the bottom dielectric substrate. On the basis of not introducing an additional decoupling circuit or decoupling element, the position of the weak field region of the electric field is changed through the dielectric resonator, so that the weak field region is located at the feed position of the coupled antenna, a good decoupling function is obtained, meanwhile, the array structure is simple, implementation and expansion are easy, and the application range is wide. The method can be applied to a multi-input multi-outpu
