✦ Synopsis

An aperture-coupled dielectric resonator antenna using a strip-line feed is in¨estigated experimentally. As compared to the pre¨ious microstrip-line ¨ersion, the new configuration eliminates the problems of backside radiation through the slot and frequency dispersion. The measured return loss, radiation patterns, and antenna gain of the new configuration are gi¨en in this letter.

In this paper, the tilt of a feedline with regard to a slot is taken into account to impro¨e the ca¨ity model, and also to see the effect of this angle on the input impedance. In fact, the angle is introduced in the ¨oltage discontinuity of the slot on the feeding line. The computed results are comp
