An Ultrawideband Monopole Fractal Antenna with Coplanar Waveguide Feed

Abstract EN

A novel ultrawideband fractal antenna in monopole configuration is proposed.

Wideband behavior and miniaturization is achieved using concentric heptagonal array structure.

Coplanar waveguide is used to feed fractal antenna.

Base shape for fractal antenna is heptagonal geometry.

Final fractal shape is achieved by performing four base shape iterations.

FR4 substrate is used for antenna fabrication.

Simulated and measured results comparison shows a bandwidth of 7 GHz with 9 GHz center frequency.

Radiation pattern of monopole fractal antenna is omni directional.

Fundamental purpose of designing and fabricating UWB fractal antenna is its application in body area networks for remote patient health monitoring.

Its application also includes C and X band frequencies.
