Abstract:

The frequency dependent characteristics of symmetric coupled microstrips in multilayer structures are considered in order to study transient signal distortion and coupling on these structures. Using the spectral domain approach with TEY LSE and TMY LSM modes, a simple recurrence relation is derived for the generalized Greens function of arbitrary multilayer structures. The frequency domain approach is used in conjunction with the evenodd mode analysis to formulate the time domain response for both of the coupled lines. Numerical results are presented for single layer structures, showing the effects of substrate materials, center conductor spacing, and line length. Results for multilayer structures are also given, showing the effects of additional substrates and superstrates on the line parameters. A new method for equalizing the even and odd phase velocities, and thus controlling the signal distortion and coupling, over a wide band of frequencies by properly selecting the dimensions and electrical properties of the substrate materials is presented.
