Abstract


In the proposed antenna design the gap coupled parasitic patches with reduced size are placed along the radiating and non radiating edges of fed rectangular micro strip patch. A patch placed close to the feed patch gets excited through the air gap or coupling between the two patches, such a patch is known as a parasitic patch. In this proposed antenna design with reduced size there is an enhancement of band width and the antenna will give satisfactory results as compared to a rectangular microstrip antenna of same design parameters without size reduction.
