Title Ultra-wideband antenna using CPW resonators for dual-bandnotched characteristic

This paper presents the design and results of a compact Ultrawideband (UWB) monopole antenna with a dualband notched characteristic. The antenna consists of a semicircular radiator and a dual-coplanar-waveguide (CPW) resonator to produce two notched bands at the center frequencies of 3.5 and 5.5 GHz in the UWB region. The computer simulation results of the Voltage-Standing-Wave Ratio (VSWR), radiation pattern and peak gain of the antenna agree well with the measurements.
