Design of flexible platform for various free-space, broadband dielectric analysis measurement techniques

This paper describes the design of a new dielectric analysis test platform, which includes controllable variable widths of MUT, antenna translation and even accurate angular positioning. This test platform will allow comparison of several frequency domain techniques, whose various aims include to lower cost, to remove diffraction and multiple reflection effects and to overcome ambiguity in the possible permittivity value. Here the target dielectrics are in powder or liquid form. The proposed test platform is a physical extension of an existing test platform, developed to qualify propagation reduction for microwave signals passing through energy efficient glass, coated with transparent conductors.
