Abstract

The edge admittance model of a microstrip structure is applied for a semi infinite conductor over a grounded uniaxial substrate using the Wiener-Hopf technique. Explicit expressions for all the scattered field components, as well as for the surface wave modes characteristic equations, are given. The TEM wave reflection coefficient in a simple closed form expression is developed, utilizing a thin substrate approximation. The effects of the anisotropy ratio on this reflection coefficient and on the characteristics of a rectangular microstrip antenna are examined.
