F-Shaped Miniaturized UWB Antenna System With Dual Notched Band Characteristics

A novel miniaturized dual notched printed monopole antenna is designed for ultra-wideband (UWB) communications. The design antenna consists of F-shaped patch loaded over FR4 dielectric substrate material with a partially ground plane. The proposed structure provides a good impedance matching having a bandwidth ranging from 3.1-10.6 GHz. Further, a rectangular split ring resonator (RSRR) structure and spiral electromagnetic bandgap (EBG) unit cells are positioned above the radiator and coupled to the feedline to obtain band-notched characteristics at 8.2 GHz, and 7.4 GHz respectively. Despite this, the antenna processes a very compact structure and have the applications over specified UWB band.
