Distributed Slow-Wavb Chebyshev Reflecfor

A frequency-selective distributed reflector based on a new crosstie overlay slow-wave coplanar waveguide is created for possible high-Q circuit applications in monolithic microwave and millimeter-wave integrated circuits. The slow-wave reflector is desiped from a transmission-line prototype which has a prescribed stopband and also prescribed Chebyshev passbands. After the conductor loss was taken into account, good agreement between theory and preliminary experiment was observed. Based on the same theory, a new slow-wave reflector created from a modified crosstie overlay coplanar waveguide is proposed and examined. Respectable slow-wave factor and a drastic reduction of conductor loss have been obtained.
