This letter presents a new low side‐lobe horn antenna with nonuniform slot array operated at K and Ka band. In the proposed antenna, the nonuniform slot array reduces the side‐lobe level by a modification of electric‐field distribution in horn aperture. The size of the proposed horn antenna is 78 × 75 × 400 mm 3 , and the experimental results exhibit a peak gain of 25–28.7 dBi and side‐lobe level of about −20 dB in target band. © 2014 Wiley Periodicals, Inc.
