摘要

Accurate equivalent-circuit models of several types of coplanar waveguide (CPW) coupling elements are presented and their parameters are derived by employing the so-called short-open calibration (SOC) technique into the full-wave method of moments (MoM). Our brief description is firstly made on the formulation of this MoM-SOC for modeling a generalized two-port CPW discontinuity in terms of its circuit network, that is, the Z- or Y-matrix. Afterwards, three sets of J- or K-inverter parameters versus frequency are extracted and obtained in order to demonstrate the comparative coupling degree of lumped-capacitive and inductive gap-coupling, as well as distributed overlapped-coupling, structures. Next, these coupling elements are utilized together in the design of compact quarter-wavelength CPW band-pass filters via a simple cascaded network topology. Our optimized results are reasonably validated by ADS simulation and both exhibit good passband behavior with broadened bandwidth of more than 20 at 5.8 GHz and an ultra-broad upper stop-band of 6.4 to 15.9 GHz.
