Efficient Evaluation of the Inner Products in the Spectral Domain Analysis of Microstrip Discontinuities
Abstract
The current trend in microwave and millimeter-wave integrated circuits (MICs) is toward higher operating frequencies, high packing densities, and more stringent performance requirements. As a result, earlier models based on approximate analysis techniques are becoming insufficiently accurate for use in computer-aided design (CAD) packages. In particular, simplifying assumptions, such as the quasi-static approximation and the magnetic wall approximation, are becoming inappropriate in the analysis of microstrip discontinuities such as bends, steps, and stubs. Instead, a rigorous full-wave analysis is needed to obtain a more accurate characterization of these passive circuits. Such an analysis captures the increasingly significant effects of coupling, dispersion, and radiation. The objective of this study is to develop an asymptotic acceleration technique for the efficient evaluation of the integrals involved in the full-wave spectral domain method for analyzing microstrip discontinuity problems.
