Abstract :
Dielectric resonator antennas (DRAs) have several advantages compared to microstrip patch antennas, such as smaller size, higher radiation efficiency, wider bandwidth, and no excitation of surface waves. This paper presents an aperture coupled dielectric resonator antenna fed by a dielectric image line. The modal expansion method is used to describe the field on the DRA side and the change in the modal voltage of the image line at the aperture is developed to analyze the single element DRA
