摘要：
In this paper, a circularly-polarized special-shaped dielectric resonator antenna working in millimeter-wave is presented. The rectangular dielectric resonator is placed above the crossed dielectric resonator to form a special-shaped dielectric resonator, fed using a microband-cross gap feeding structure. This feed circuit is used to achieve circularly-polarized and improve the antenna bandwidth. Simulation shows that the antenna works in the 23.57GHz-28.4GHz band with an impedance bandwidth of 18.9% and axial ratio bandwidth of about 7.4%.
