A hexagonal‐shaped fractal antenna with triangular slot for super wideband (SWB) application is presented. The proposed antenna has total size of 20 × 33.4 × 1.57 mm3.The proposed antenna is designed of iterations of triangular slot on a hexagonal metallic patch with tapered microstrip line feed. A combination of semicircular and rectangular shaped partial ground plane is used to achieve a super wide bandwidth from 3 to 35 GHz with bandwidth ratio of 11.6:1. The antenna design, simulation and optimization are performed using IE3D Full Wave Electromagnetic Simulator. The proposed antenna is compact and has stable radiation pattern. The simulation and measured results are compared to demonstrate the performance of proposed antenna. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1659–1662, 2015

The article presents the design of triangular shaped fractal based antenna with circular slot for ultra wideband (UWB) application. The antenna is fed using microstrip line and has overall dimension of 24×24×1.6 mm

A Novel coplanar waveguide (CPW) fed Ultra Wideband (UWB) antenna is presented. The proposed antenna is designed on RT/duriod 5880 substrate with thickness of 1.57 mm and relative permittivity of 2.2 having loss tangent 0.0009 using a second iteration Sierpinski carpet fractal with overall dimension of 37 mm x 46 mm x 1.57 mm. The designed antenna offers a good impedance bandwidth from 3.1 to 11 GHz. The presented antenna has omnidirectional radiation pattern and good gain flatness suitable for UWB applications.
