The invention relates to the technical field of radar auxiliary antennas, in particular to a microstrip patch oblique polarization directional cancellation antenna which is suitable for a radar directional auxiliary cancellation antenna system and can improve the anti-interference characteristic of a radar. The directional auxiliary antenna is divided into three one-to-four micro-strip power division network column line sources, each column comprises four oblique polarization micro-strip antenna units, and the three columns of oblique polarization micro-strip antenna line sources are distributed in a triangular shape. The oblique polarization microstrip antenna unit is formed by rotating the horizontal polarization microstrip antenna unit by a certain angle. Each column of antenna units adopts equal-amplitude unequal-phase weighted synthesis, the phase weighted value is a certain phase difference, and the phase weighted value is realized by a one-to-four power division network column line source network.
