“…2 which also shows schematically the sampling functions. For comparison purposes, we also include in this work a one-dimensional (1-D) analysis, where no singularities are considered and the test functions are reduced to the following triangular sampling functions: (6) In (6) is the unknown amplitude of the current at the center of the cell When a two-dimensional (2-D) analysis is performed, the test function includes the straight edge singularity and can be formulated as follows: (7) In the three-dimensional (3-D) treatment, (7) holds for the body cells, whereas for the corner cells the test functions must fit the vertex conditions as follows: (8) is the radial distance from the tip A in Fig. 3 and (see in [3, (5), as shown in the next section.…”

“…In order to validate these hypotheses, I have made some significant changes in the dimensions of the box and then the variations in at 4, 18, and 22 GHz were determined. Unfortunately, the actual measurement techniques for this accurate frequency dependence suffer from repeatability measurement errors (see [6], [8]). …”

This study presents the original inclusion of right singular vertex conditions in integral equations solved by the method of moments for accurate evaluation of frequency-dependent microstrip discontinuity models required in microwave integrated circuits (MIC) and monolithic microwave integrated circuits (MMIC) design. The 90 wedges singularity function for the current density, weighted with a novel sampling function for "corner cells," and the harmonic Green's function for shielded structures, is accurately and efficiently integrated in the conical geometry of the 90 sector. The frequency-dependent effective length and excess equivalent capacitance of a shielded open-ended microstrip line are calculated to a higher accuracy with respect to previous two-dimensional and three-dimensional "full wave analyses." Index Terms-Microstrip transmission line, printed antennas.

“…This work deals with the determination of the capacitance parameters of the equivalent circuit of the AECMOED by means of a static method of analysis. Although in practice these capacitance parameters are frequency dependent, their static limit value is expected to be approximately constant in a wide frequency interval for the range of dimensions usually employed in microwave integrated circuits [9].…”

A lumped capacitance equivalent circuit is used to characterize the asymmetric edge‐coupled microstrip discontinuity in the case in which the conducting strips are embedded in a multilayered anisotropic medium. The Galerkin method in the spectral domain is employed to determine the excess charge density on the strips of the discontinuity. Original results are provided for the general asymmetric discontinuity in conventional and suspended configurations. © 1992 John Wiley & Sons, Inc.

A comparison of different methods for the characterization of planar line discontinuities with emphasis on microstrip discontinuities is given, thereby describing the present state of the art in this area of microwave circuit CAD. Quasi-static equivalent circuit models, the magnetic wall waveguide model of microstrip discontinuities, full-wave analysis techniques like the orthogonal series expansion and mode matching techniques, the spectral domain analysis technique using roof-top functions, and the finite-difference time-domain technique are described briefly and compared with respect to their numerical eaciency and their capabilities.
