A Microwave Measurement System for Measurement of Dielectric Properties
Poster (konferens), 2014

We present a prototype of a microwave measurement system for the estimation of dispersive dielectric properties. The measurement system consists of a metal cavity that features a measurement region in the center formed by the intersection of six rectangular waveguides. The waveguides are terminated by adapters connected to coaxial cables. We exploit the frequency band 2.7-5.1 GHz and a connected network analyzer and switch allows for automatic measurements of the 6-by-6 scattering matrix S. We estimate the complex effective permittivity of densely packed MCC (micro-crystalline-cellulose) pellets over frequency for different moisture contents. This material is used in pharmacutical processes.
