This paper presents a monopole antenna with three-tier small semicircles for ultra-wideband operation. The monopole antenna with three-tier small semicircles which can get wider bandwidth is done by etching process on the FR4 substrate with 1.6mm in thickness and 4.4 relative permittivity. The ground plane is a semicircle with larger slit which is good for impedance matching. The S11 frequency response,...
