Abstract
A new coplanar waveguide bandstop filter using capacitively loaded spiral-shaped resonator is proposed. The filter consists of a rectangular stepped coplanar waveguide and a spiralshaped slot in the center conductor. By embedding capacitor in the spiral-shaped slot, tunable bandstop filter can be implemented, and tuning range from 1.5 to 3.0 GHz have been obtained.
