A Fibonacci series‐inspired‐elliptically‐slotted CPW fed UWB patch antenna with Ku band‐reject characteristics

This letter introduces a compact elliptically‐slotted patch antenna with Ku band reject characterizes. The proposed antenna works in the super wide range of frequency band stretched beyond the UWB. The slots in the radiating patch take the shape of ellipse and are present in such a manner that the d...

Description
Summary:This letter introduces a compact elliptically‐slotted patch antenna with Ku band reject characterizes. The proposed antenna works in the super wide range of frequency band stretched beyond the UWB. The slots in the radiating patch take the shape of ellipse and are present in such a manner that the double of their ellipticity follow the Fibonacci series. The perturbed‐diamond‐shaped patch without the slot radiates in the frequency range from 4.19 to 21.88 GHz with a bandwidth of 17.67 GHz. The same patch antenna with the elliptical‐slots rejects Ku band from 12.89 to 16.22 GHz. We have analyzed the notch frequency variation with respect to the slot area using Ansys HFSS V.20 electromagnetic simulator software for verification.
