Abstract

This paper deals with the design of a dielectric resonator antenna (DRA) with symmetrical radiation pattern to be used as an integrated feed for a Half-Maxwell Fish-Eye dielectric lens antenna. The dielectric lens and its feed are designed to be both manufactured with 3D-printing. The entire lens and feed are implemented with four commercial filaments, reaching the needed refractive indexes varying the infill percentages. This feed allows multibeam operation or mechanical scanning, operating at a central frequency of 28 GHz.
