Design of Compact UWB Coplanar Waveguide-Fed Modified Sierpinski Carpet Fractal Antenna

摘要

In this paper, a compact coplanar waveguide-fed planar fractal antenna for ultra-wideband (UWB) applications is designed. The proposed approach consists of two iterations modified Sierpinski hexagonal slots with hexagonal radiation patch and CPW feeding. It has a simple structure with compact size of 16.5×14.5 mm~2. An impedance bandwidth of 112.2% (3.03-10.77 GHz) is achieved, with a maximum peak gain of 3.74dBi at 8.15 GHz. With these promising features, this antenna is suitable for UWB communication applications.
