A Circularly Polarized Fibonacci Series-Inspired-Elliptical Patch Antenna for UWB Radiation

In the manuscript, a compact dual-band antenna with rectangular slot on ground plane and a novel Fibonacci inspired patch is presented. The ellipse is arranged in such a manner that half the major axis follow the Fibonacci sequence. Later the bandwidth is increased and it is configured to a UWB antenna by incorporating circular sectors and L-shaped strip to the rectangular slot. The final antenna radiates in the frequency range from 3.10 GHz to 14.58 GHz with a bandwidth of 11.48 GHz. Further, a ‘≠’ shaped strip is inserted on the ground plane to configure the circular polarization behavior of the antenna. It has stable radiation pattern and usable gain over the entire frequency band. Ansys HFSS V.20 Electromagnetic simulator is used for design purpose.
