Abstract
Abstract A microstrip patch or slot radiating element is coupled to a dielectric rod antenna by way of a tapered tubular dielectric guide formed integrally with the rod. An array of radiating elements may be formed on a common substrate, and the dielectric guide/rod antennae may be arranged to direct the energy radiated from these elements to a secondary antenna element such as a lens or a dish.
