This antenna is obtained by rounding and notching the edges of antenna arms. Antennaparameters for the designed structure are examined according to the restrictions specified by FederalCommunications Commission. Thus, Return Loss (S11), Voltage Standing Wave Ratio (VSWR), gain,radiation pattern and impedance are observed in the 3.1 GHz - 10.6 GHz frequency range. Additionally,the effect of arm length and dielectric material on antenna performance are interpreted in the same range.According to obtained results, the proposed structure satisfies the bandwidth requirements for Ultra-Wideband systems. Gain and impedance variations are also in acceptable limits for Ultra-Widebandapplications. The proposed antenna is analyzed through CST Microwave Studio program.eninfo:eu-repo/semantics/openAccessArticle9048536594124
