Abstract : The patent application relates to the unwanted higher order mode power that occurs in flared antenna horns which is compensated for by inserting flare sections into the antenna horn feed structure. The feed structure flares also generate higher order mode power and are positioned and constructed in such a manner that the higher order mode power so generated is substantially equal to and in phase opposition with the higher order mode power occurring in the antenna horn. Various embodiments use single outward, double outward and double inward flares.
