Abstract :
A modified dielectric cone-loaded horn is described that maintains excellent return loss and pattern symmetry over a bandwidth ratio greater than 30:1. The mechanisms responsible for the extremely broadband operation and its application as a feed horn for a reflector antenna are discussed
