CPW feed circular monopole antenna for UWB applications with notch characteristics

This paper presents the design of a coplanar waveguide (CPW) fed ultra wide-band circular monopole antenna for UWB communication with frequency notch characteristics. The electromagnetic coupling of the SRR with the CPW yields the frequency notch. The impedance and radiation plots confirm the suppression of the desired notch frequency. A theoretical formulation to calculate the notch frequency is also proposed and validated. The performance and characteristics of the antenna are investigated by FEM technique and better results were obtained in order to understand its operation.
