J. Cain et B. Beker, ANALYSIS OF MICROSTRIP DISCONTINUITIES ON SUSPENDED AND GROUNDED ANISOTROPIC SUBSTRATES, Microwave and optical technology letters, 9(2), 1995, pp. 77-83
This article presents a comprehensive numerical study of resonant and
nonresonant microstrip discontinuities that are printed on anisotropic
substrates. The approach employs the method of moments (MoM) which is
implemented for the gap, step, and slub discontinuities for the first
time in MICs with other than biaxial anisotropic substrates. Numerica
l results include the variation of the normalized gap admittances with
respect to different material parameters, insertion and transmission
loss of step discontinuities, and shifts in resonant frequencies of tu
ning stubs due to rotation of the principal axes of the substrate. Com
puted data are validated for every structure against results in previo
usly published literature. (C) 1995 John Wiley & Sons, Inc.
