Abstract

A compact Super ultra-wideband (SUW) antenna is discussed in this work. A rectangular radiator is modified into a tree-shaped structure with the defected partial ground to enhance the operating bandwidth. The novel rectangular parasitic with the circular slot is used as a notch in the ground plane which prevents the WLAN frequency. The proposed SUW antenna is achieving the 10 dB impedance bandwidth (IBW) from 3.5 GHz to 66.5 GHz frequency with a notched band varying from 5.0 GHz to 5.4 GHz. The bandwidth ratio (BDR) of the proposed SUW antenna is 1773.4 whereas the obtained bandwidth percentage (BW %) is 180. A modified SRR frequency selective surface (FSS) is designed for UWB application to improve the gain of the antenna. The compact unit cell of FSS is having electrical dimensions of 0.16λ0x  0.16λ0 The antenna achieves the maximum realized gain 9.46 dB when FSS is loaded as a superstrate and up to 5.2 dB gain enhancement is observed in the UWB frequency.
