  • Abstract
    A simple lens concept that transforms the aperture field of a conical horn antenna driven by an azimuthally symmetric mode is presented. It is shown that with the appropriate lens geometry the radiated field of the conical horn will exhibit a boresight null (no lens), a boresight peak with linear polarisation, or a boresight peak with circular polarisation
