## Abstract A new formula for the wide aperture dimension of a pyramidal horn is presented. It is obtained by using a particleβswarm optimization (PSO) algorithm, and is used in successfully designing optimumβgain pyramidal horns. The computed gains of the designed pyramidal horns are in very good

Three formulas for the narrow and wide aperture dimensions of the pyramidal horn are improved, and the improved formulas give lower average percentage errors (0.00452, 0.01566, and 0.00809%), compared to the average percentage errors of three available formulas (0.01497, 0.27561, and 0.07268%). The
In this work, we apply classical and new self-adaptive differential evolution (DE) algorithms to the design of optimum gain pyramidal horns. The application of DE algorithms to pyramidal horn design allows the accurate calculation of their physical dimensions in a short amount of time. Moreover, sel
