Abstract
This study proposes a compact resistively loaded dipole antenna (CRDA) for imaging applications. The triangular tapered transmission line has been introduced to feed the balanced structure of the CRDA and 78.5% of energy was successfully delivered to the end of the transmission line. The fabricated CRDA, which was fed by the triangular tapered transmission line, has been analyzed in terms of the characteristics of its reflected pulse and current distribution for image quality aspects by comparing it with a conventional dipole antenna (CDA). Using the CRDA, the imaging experiment for a perfect electric conductor (PEC) target and fabricated a multi-layered head phantom was performed. With this experiment, the target image has been successfully reconstructed by the delay and sum technique in the end.
