A probe-fed 3D-printed rectangular dielectric resonator antenna (RDRA) for 2.4/5.2-GHz wireless local area network (WLAN) applications is demonstrated in this study. It validates the first successful utilization of Barium Titanate (BaTiO3) powder and UV-curing resin in conjunction with Stereolithography Apparatus (SLA) 3D printing technology to create a ceramic DRA with a dielectric constant of 8. Through using notched slots and a folded metal strip on the antenna structure, three distinct modes within the designed RDRA are excited, achieving complete coverage of the 2.4/5.2-GHz frequency bands. An agreement between the simulated and measured results is achieved, highlighting the potential of the SLA technique for future DRA designs and applications.
