Abstract :
Dielectric resonator antennas have been developed for the use in microwave and millimeter frequency bands; they have several advantages over the microstrip patch antennas such as smaller size, higher radiation efficiency, wider bandwidth, and no excitation of surface waves. Recently, the aperture coupled rectangular DRA fed by a microstrip line was analyzed. This paper presents an aperture coupled dielectric resonator antenna and arrays fed by dielectric image line (DIL). In exciting the DIL, the DIL is connected to the X-band rectangular waveguide three-section transition in order to reduce the return loss. HFSS commercial software was used to obtain the results for the transmission coefficient, return loss, and radiation patterns
