Ultra-wideband monopole antenna for multiband and wideband frequency notch and narrowband applications

摘要

A new design concept of a multi-configuration antenna providing both frequency notched ultra-wideband and multiple narrowband functionality from a coplanar waveguide fed circular monopole antenna is presented in this study. The proposed multiple antenna configurations are achieved by loading the feed section of the antenna with circular split ring resonator pair of varying dimensions and inner ring orientations and shorting copper strips. Fabricated prototypes were measured and compared with simulation and good agreement is obtained for both impedance and radiation characteristics.
