Abstract—In this paper, the design of a circular corrugated horn antenna is presented for low sidelobe-level. The basic requirement of this design is compactness. Therefore, we use corrugated Gaussian profiled horn antennas to improve the size and sidelobe level simultaneously. Because of compact design of this horn, it is not expected to have a good symmetry in E and H planes. The obtained radiation patterns are sufficient for desired applications. The proposed corrugated antenna has a longitudinal section composed of a normal corrugated horn, some straight corrugations, and a Gaussian profile to complete transition between waveguide and the free space.
