This paper presents a 3D-printed prototype of a novel top-metalized Dielectric Resonator Antenna (DRA). The
inclusion of top metallization induces a modification in the boundary conditions, resulting in a frequency reduction in the
fundamental mode of the DRA. Still, it does not degrade its radiation performance. The dielectric part is manufactured using
fused deposition modeling (FDM) printing techniques and a commercially available Zirconia-loaded filament. The prototype
presents a –10-dB bandwidth from 2.54 to 2.68 GHz with a minimum of –21 dB at 2.60 GHz. The radiation maxima occur
in the top and bottom directions, with a simulated gain of 2.7 dBi. Thus, a low-cost and fast method to implement and manufacture
a miniaturized DRA is presented.
