An evolutionary progranirnitzg (EP) algorithm is used to optimize pattern of a corrugated circularhorn subject to various constraints on return loss and antenna beamwidth and pattern circularity and low crosspolarization. The EP algorithm uses a Gaussian mutation operator. Examples on design synthesis of a 45 section corrugated horn, with a total of 90 optimization parameters, are presented. The results show excellent and efficient optimization of the desired horn parameters.

In this thesis an analysis is made of the radiation patterns produced by electromagnetic wave guides and horns of variously shaped cross sections. The theoretical approach is based on the concept of equivalent electric and magnetic surface currents, and it explores a method that has been suggested by S. A. Schelkunoff. No attempt is made to develop design formulae since they are adequately known from empirical data.
