The revolution that wireless communication is suffering during the lastdecades has increased the need for antennas where performances such aslightweight, rapid manufacturing and portability run in parallel with theirelectric performance. The maker revolution in which 3D printers can helpmanufacturing customized, high performance, lightweight and rapid manufacturingantennas is a fact to be explored. This paper discusses the design, simulationand 3D printing of an offaxis reflector antenna. The proposed design iscomposed of a parabolic reflector and an X band circular horn antenna as afeed. By adding a dielectric rod waveguide (DRW) to the feed, a rotationallysymmetric radiation pattern, similar to the one with a corrugated horn, isachieved.
