occurring when the aperture dimensions are A ∼ = √3λLandB = 0.81A. The principal-plane beam- widths for the optimum horn with maximum gain are given by θB ∼ = 54λ/B in degrees in the yz- plane, and by φB ∼ = 78λ/A in degrees in the xz- plane. For a pyramidal horn, with A = 6λ and B = 4.86λ, at 6 GHz, ?nd GD, θB, and φB. Comment on whether this horn is optimum.
