Microstrip antennas find far-reaching applications in the current communication scenario due to their unique properties
like light weight, ease of fabrication, low production cost, low profile, etc. But the fields of application of these antennas are limited by their inherent disadvantage of relatively lowimpedance BW. Bandwidth enhancement is needed in order to
fulfill the requirement of today’s communication systems.Many bandwidth enhancement techniques have been proposed
by researchers7-15. They achieved wide bandwidth, but they changed the antenna structure and increased complexity of the system. In 1998, J. George proposed that the BW of a microstrip patch antenna could be increased by loading a DR
on the patch surface [5]. In this paper, we have reported an optimization of the height of the DR on the antenna and
effects of its dielectric constant on the antenna properties. We studied the effects of loading the DR on feed point and making
