Abstract: In current scenario, many researchers are focused on antenna design with an emerging technology of ultra-wide band (UWB) applications. UWB provides many advantages such as high gain, low VSWR, minimum return loss and omni-direction radiation pattern which are best suitable for medical applications. The US Federal Communications Commission (FCC) has a frequency band of (3.1-10.6) GHz for this research. In this paper, a novel rectangular stair slot (RSS) antenna is proposed to achieve UWB with simple structure and compact size. The overall size of the designed antenna is 33 × 19 × 1.9 mm³ with FR4 substrate. It is fed with 50 Ω micro-strip lines with a truncated ground line. In addition, bandwidth is enhanced by introducing the step-cut in the left corner of radiating patch. The proposed antenna is simulated in Ansoft HFSS simulator. The performance of antenna is exhibited by investigating a various parameters such as return loss, VSWR, gain, directivity, impedance, group delay and radiation pattern. The designed antenna is fabricated with eleven lab and measured with the help of vector network analyser.
