Our main objective in this project was to offer the design of 3 wideband microstrip patch antennas. In fact, Microstrip antennas have the exciting qualities of low profile, light in weight and simple structure. Having said that, its bandwidth is constrained to a few % which isn’t really enough for the majority of wireless communication systems at present. A couple of bandwidth enhancement methods are actually advised like making use of thick foam substrate, cutting 1 or 2 U-slots on the patch, stacking one more patch over the original one and making use of shorting pins.
This thesis presents the design and development of several novel small and wideband patch antennas. Microstrip antennas have the attractive features of low profile and light weight. However the antennas may be too large for practical applications at the lower microwave frequency
