In this paper, the design, and performance analysis of an Ultra-Wideband Antenna (UWB) is proposed. The Ultra-Wideband Antenna is found capable enough of working over an UWB range as allocated by Federal Communications Commissions (FCC) with good antenna properties over the frequency range. The antenna has been designed using Flame Retardant 4(FR4) substrate of dielectric constant, εr=4.4 and height of dielectric substrate, h=0.1566 cm. A microstrip line fed rectangular patch antenna is made to undergo several slot cuts to ensure that it has better Return Loss S11 < -10dB, Peak Gain, Efficiency, and Radiation Pattern. This staircase-shaped design with a Defective Ground Surface (DGS) has wide impedance bandwidth measured at about 9.95 GHz (3.22 GHz-13.17 GHz), bandwidth ratio about 1:4, VSWR less than 2. The antenna structure is flat, and its design is simple and straightforward geometrically small, hence embedded easily in various applications like Medical Imaging and Point-to-Point (P2P) Microwave Radio Links. The simulation and analysis were done using High Frequency Structure Simulator (HFSS).
