Abstract
An apparatus for broadening the radiation pattern of a waveguide horn includes an input waveguide feed including a non-circular waveguide horn having a non-circular aperture, and a dielectric lens shaped as a toroid having an interior opening and an outside circumference, the toroid being cut along an imaginary plane extending generally parallel to a diameter of the toroid and being positioned generally coaxially adjacent the non-circular aperture.
