Abstract
A multi-step circular horn system may have several steps and may use more than one flared section based upon design considerations. In order to achieve high aperture efficiency, the aperture field distribution is close to uniform. For good cross-polar performance, the field distribution is circularly symmetric. Location and shape of the steps is determined by the wavelength of the signal being transmitted and the space constraints imposed by the antenna design. The step discontinuities generate desired modes of operation in the right proportion.
