Abstract: In this manuscript, a compact printed ultra-wideband (UWB) monopole antenna having a split ring resonator with a slotted radiating element is presented. The enhancement of the bandwidth of the proposed antenna and a preliminary notch creation at 4.7 GHz is accomplished by a square shaped slot in the radiating element of the circular size and also by erection on open-ended split-ring from the upper portion of the square slot in the radiating element. The fine tuning of the notch frequency at 5.5 GHz in the WLAN band (5 GHz-6 GHz) is achieved by incorporation of a split ring resonator (SRR) on the left hand side of the microstrip feed-line. Impedance bandwidth of 3.097 GHz to 13.326 GHz (fractional bandwidth of 125%) is provided by the proposed antenna. The proposed antenna provided simulated and measured gain of 5.5 dBi-6.0 dBi for the entire UWB band of operation except the WLAN's notch band. The proposed antenna is compact in nature (17 × 15 mm²) and also the equivalent circuit and time domain analysis for the proposed UWB notch antenna are also suitably developed.

Keywords: monopole; ultra wideband; UWB; split ring resonator; SRR; slot; slit ring; micro strip; time domain; fidelity factor.
