✦ Synopsis

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 agreement between the desired gains and the computed gains of the horns designed by using the improved formulas is very good, having average percentage errors of approximately 0.0017-0.0063%.

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