Slot-aperture-coupled linear dielectric resonator array fed by dielectric image line backed by a reflector

The aperture coupled dielectric resonator antenna array fed by dielectric image line backed with a reflector was simulated using HFSS. A good return loss was obtained for an array of 7 DRA elements by adding cancelling slots with the radiating slots. Adding a reflector in the DIL side decreases the back radiation and increases the gain for the array.
