Characterization and Formulation of Microstrip-Slot Impedance with Different Thickness and Relative Permittivity

Abstract:

This paper presents the characterization of a microstrip-slot line in terms of its impedance and dimension. The characterization is made by referring to the analysis of different relative permittivity and thicknesses of substrates, which conducted by using CST Microwave Studio. Based on the characterization with the use of completing square curve fitting method, new formulated equations are proposed for microstrip-slot line. These formulated equations are suitable for thin substrate with low relative permittivity. The characterization is made based on the substrates with the selected thickness of 0.508 mm, 0.762 mm and 1.542 mm, for relative permittivity of 4.5 (TMM4), 3.38 (RO 4003C) and 2.94 (RT 6002).
