Abstract

Closed form expressions for the Green's functions of a planar microstrip structure on an electrically thin uniaxially anisotropic substrate have been derived. The approach is to first obtain the quasi-dynamic term and refine its accuracy with a correction term valid for higher frequencies. The quasi-dynamic term conveys the influence of partial images and includes both transverse and vertical dielectric constants εrt and εrz. The correction term, on the other hand, results in an expression that includes εrz only. Results indicate excellent agreement with exact numerical solution over a significant band of frequencies and over a large range of spatial values.
