This paper is aimed to focus on bandwidth enhancement of a slot antenna with coplanar waveguide feeding. The experimentation is performed on the general CPW structure which is having a signal conductor in the middle and two ground layers etched on either side of feed with some gap to allow a unique feature of uniplanar in construction. In this context, the study of a CPW transmission line discontinuity is applied to prepare a slot antenna and this is followed by the study of incorporating serrated shape in the structure.
