Multiband fractal slot antenna with closed ground structure

Abstract

This article presents a multiband slot antenna with closed ground structure and coplanar waveguide feeding. The fractal structure is attained by placing multiple slots in a particular orientation on the radiating element. The ground plane was constructed on same side of the substrate along with fractal-structured patch in closed loop orientation. The designed antenna is resonating at multiple bands, which include Wi-Fi, Wi-MAX for mobile communication systems. The antenna properties like return-loss, gain, radiation pattern and field distributions are analysed through electromagnetic simulation and measurement.
