Abstract

A coupled-microstrip lines (CML) structure with a backside aperture is proposed for use in the innovative design of M(H)MIC-based multilayered bandpass filters. This aperture technique is used to compensate the coupling characteristics of CML. With the “short-open calibration” (SOC) scheme self-contained in our full-wave method of moments (MoM), its parametric coupling behavior is investigated in detail. The SOC-extracted lumped circuit parameters are expressed in terms of Y-matrix and J-inverter network, respectively. Our obtained results show the attractive merits of the proposed technique in enhancing the desired coupling, which is useful for the design and realization of a low-loss wide bandpass filter using the 3-D multilayered M(H)MIC technology
