Abstract :
A method to form a notch band is presented. We etch complementary split-ring resonators in the T-stub region of a CPW-feed ultrawideband (UWB) antenna. Due to limited space in this region, we connect two resonators together so that they have a common slot edge. Compared with two separated CSSRs, this new design not only occupies less space but also yields high mismatch losses. It is found that high mismatch losses and deep suppression level can be obtained at the desired notch band.
