The worldwide deployment of 5G wireless networks has necessitated property characterization for dielectric materials at higher frequencies. Copper clad laminates, antennas, radomes, and other applications related to connectivity rely on the dielectric permittivity (Dk) and dielectric loss (Df) performance of materials to meet device-specific requirements. Dielectric materials are often supplemented by various additives and fillers to alter mechanical, thermal, and visual properties, which can potentially influence dielectric properties. This talk will explore the impact of common colorants on plastic dielectric properties over multiple frequency ranges: 20 Hz – 1 MHz, 100 MHz – 1 GHz, and 1 – 10 GHz. This is accomplished through application of parallel plate and split post dielectric resonator techniques. Special attention will be paid to different classes of colorants, including organic dyes and pigments, inorganic pigments, and other fillers. Results from these studies will be compared to effective medium approximations to establish predictive tools for dielectric properties.
