Planar antenna arrays with wide angular scanning capabilities have been an important issue. This paper proposes a new method for reducing the sidelobe level (SLL) of phased arrays. By changing the arrangement of the feed points and different phase differences of each unit antenna, the side lobes on the horizontal plane can effectively reduce bad effects. Through CST simulation, it is demonstrated that the side lobe reduction effect meets the requirements of the Ka-band.
