Design an optimal pyramidal horn for optimum operation at 1 GHz and a gain of 15.45 dB. It is connected to WR975 waveguide with a=9.75 in = 24.765 cm and b=4.875 in. = 12.3825 cm. Also determine the half-power bandwidths in the E- and H- planes. Give all dimensions in cm. Check to make sure your design has the correct optimum phase delay in the E- and H- planes (s=1/4, t=3/8)
