Abstract :
A thorough and systematic investigation of resonant phenomena in conductor-backed coplanar waveguides (CBCPWs) is reported. A rigorous three dimensional full-wave space-domain integral equation method accompanied by an S-parameter extraction technique is used. A series of measurements has been conducted to confirm the theoretical results. A patch-resonator model and a microstriplike (MSL) model are employed to understand the origin of resonance existing in one of the test circuits. The 3-D program is also invoked by displaying the current distributions to help visualize how the CBCPW test circuits work at both through and resonant states. The results obtained validate the conclusions drawn for the patch-resonator model and the MSL model
