Abstract

Accurate and precise knowledge of the relative permittivity of printed
circuit board (PCB) materials is essential for the reliable design of
high-frequency circuits. For simplicity reasons, planar, resonant
permittivity sensors, which are directly integrated on the unknown PCB
material, are widely used. However, the sensors are affected by the
nonidealities of the copper-clad laminate and PCB manufacturing process,
e.g., the difference in roughness between the top and bottom sides of
each metal layer. This paper analyzes the influence of these
nonidealities on the extracted relative permittivity values of different
sensor geometries in microstrip and substrate integrated waveguide
(SIW) technology up to 100 GHz. Microstrip resonators are very sensitive
against the investigated nonidealities. Additional roughness
measurements and more detailed simulation models cannot noticeably
reduce the uncertainties. SIW cavity sensors are more robust, and simple
modeling approaches lead to low uncertainties smaller than 0.05 for the
whole frequency range from 10 to 100 GHz.
