The present invention relates to a circularly-polarized dielectric resonator antenna (DRA). The antenna comprises a substrate, a Wilkinson power divider, a phase shifter, a ground plane and a dielectric resonator, wherein the phase shifter is connected to the Wilkinson power divider. Besides, the dielectric resonator is disposed on the ground plane, and includes a dielectric main body and a slot disposed above the substrate. Additionally, the antenna is adopted to increase the linear radiation bandwidth by utilizing the slot, and transceives a circularly-polarized electromagnetic wave by utilizing the Wilkinson power divider. Consequently, the circularly-polarized dielectric resonator antenna can be applied in the fields of satellite communication, Worldwide Interoperability for Microwave Access (WiMAX), and wireless communication.
