Investigation of Planar Waveguides and Components for Millimeter-Wave Integrated Circuits.

Abstract

Several important elements in millimeter-wave integrated circuit systems are studies. Filter-type structures which are composed of a series of discontinuities are employed frequently in such systems. The study of the general discontinuity problem is thus very important. The uniform fin-line structure is analyzed by using a spectral domain formulation with a moment method solution. This results in data for phase constants, mode functions and characteristic impedances. Two fundamentally different approaches for solving the discontinuity problem are presented. The first involves formulating the problem using unknowns in the plane of metallization, and both a single discontinuity and an infinite array of discontinuities are studied. Solutions are obtained using a moment method in the spectral domain. The second approach uses unknowns in the transverse junction plane. Solutions using the conjugate gradient iteractive method and the generalized variational procedure are studied. Scattering parameter data for several examples is presented.
