CPW fed Arc shaped UWB slot antenna for on body applications

Abstract

In this paper, we introduces Arc shaped UWB slot antenna fed by CPW. This structure is designed for wireless on-body applications. The dimensions of proposed structure is 33 × 31 × 1.6 mm3, which is developed by using a FR-4 substrate. The dielectric constant of 4.4 and thickness chosen for this design is 1.6 mm. The defective ground structure and bio-skin layer at bottom of the antenna is introduced to improve performance of the antenna for on-body communication. The proposed antenna will provides two resonant frequencies 5.12 GHz and 7GHz and their reflection coefficient values are −13.52 dB, −20dB and also discussing computer simulation results like return loss, VSWR, gain, radiation patterns, efficiencies and surface current.
