Based on an open-ended flanged coaxial probe technique, this paper measures complex permittivity of flake dielectric materials loading at the end of a probe. The method compares measured values and theoretically calculated values, the measured values being processed by optimization iteration computation. This paper introduces a theoretical model and the measurement system in detail. Feasibility and rationality of the presented method are shown by measuring some common materials.
