The invention discloses a filtering antenna array based on dielectric resonators. The filtering antenna array comprises a dielectric substrate and a metal ground plane from bottom to top; a feed mechanism is mounted on the lower surface of the dielectric substrate; a gap is formed in the metal ground plane; a first radiation unit, a second radiation unit and a third radiation unit which are arranged in a row are mounted on the upper surface of the metal grounding surface; the first radiation unit and the second radiation unit are connected through a first dielectric bridge, and the second radiation unit and the third radiation unit are connected through a second dielectric bridge; the lower surfaces of the first dielectric bridge and the second dielectric bridge are attached to the upper surface of the metal ground plane. On the basis of not introducing an additional filter circuit or filter element, through the resonance of the metal parasitic strip and the half-wavelength characteristic of the metal microst
