Abstract

The resonant phenomena found in CBCPW integrated through line are investigated in detail both experimentally and theoretically. Two CBCPW through-line test circuits have been built and tested. One has uniform side planes and the other contains two slits in the middle of the side planes. Three techniques are used to investigate the resonant phenomena, namely, the patch antenna cavity model, the multimode model, and the full-wave space-domain integral equation approach. The measured transmission ( mod S/sub 21/ mod ) and reflection ( mod S/sub 11/ mod ) characteristics of the through lines are reported. At a representative resonant frequency of the measured data, current distributions are displayed, demonstrating that the side planes of the CBCPW contribute to the resonance in a way similar to planar patch antenna or 2D planar circuits.>
