Abstract
Periodically series‐capacitive loaded transmission line on coplanar waveguide (CPW) is studied in this work as a planar 1D guided‐wave medium. The two effective per‐unit‐length transmission parameters, that is, propagation constant and characteristic impedance, are numerically extracted to demonstrate the guided‐wave characteristics in a frequency range covering the first stopband, first passband, and second stopband. To further provide a proof, the six‐cell periodic CPW with impedance transformers at two sides are designed and fabricated. The predicted S‐parameters are well confirmed by the measured ones. © 2005 Wiley Periodicals, Inc.
