An offset fed split ring resonator (SRR) based compact printed antenna is analyzed for Ultrawide-band (UWB) applications. The suggested antenna has been designed and analyzed using High frequency structure simulator (HFSS) on a low-cost FR-4 substrate. The top plane of the designed antenna consists of circle and semicircle combined split ring resonator (SRR). The partial rectangular ground along with a semi-circular slot is introduced on the back side of the substrate for impedance matching improvement in all over the wide range of frequencies. The offset feed is used for the adjustment of radiation pattern. The fabricated antenna prototype is realized and experimentally tested to authenticate the results obtained from simulation study. This proposed antenna covers the UWB range extending from 3.8 GHz to 14.9 GHz. The proposed compact antenna dimension is 18  20  1.6 mm3. The proposed antenna achieved a maximum gain of 15 dB at 3.8 GHz. It maintains stable radiation patterns across the operating band. Hence, the obtained results and compact size of the proposed antenna is ideally suited for various wireless applications including wireless local area network (WLAN), Internet of things (IOT), X-band satellite communication, and UWB systems.
