Abstract :
It is shown that ray theory can be used in designing a microwave horn with a hyperbolic secant refractive-index profile. The horn is short in length, has constant phase across the plane aperture and tapered illumination in the E-plane, resulting in a radiation pattern with low sidelobes. Experimental verification has been made on a model operating around a frequency of 10 GHz.
