Abstract

A compact novel lamp slotted upper WLAN band rejected ultrawideband (UWB) radiator integrated with Ku and partial K bands is reported. The intended radiator consists of a novel lamp slotted patch structure with a 50 Ω tapered microstrip feed line along with a novel semicircular defected ground structure (SCS-DGS). The size of the suggested radiator is 16×22 mm² with an impedance bandwidth ranging from 3.63 to 21.94 GHz to cover UWB integrated with Ku and partial K bands, and a novel via notched element is utilized to notch the upper WLAN band from 5.31 to 6.05 GHz. The proposed antenna has stable radiation patterns, consistent gain, and a peak radiation efficiency of 92.15% except for the notched band which mak it suitable for upper WLAN band notched UWB wireless communication applications.
