Preparing for 6G: Developing best practices and standards for industrial measurements of low-loss dielectrics

With growing interest in millimeter-wave (mmWave, 30 GHz – 300 GHz) technologies, researchers and manufacturers need standard reference materials and best practices for measurement validation, material acceptance, and quality assurance. Today, there is no standard reference material for dielectric permittivity and loss tangent in the mmWave regime. Here, we show the results of round robin experiments that evaluate the current state-of-the-art methods in dielectric measurements. Due to the wide spread in these results, we identify the need for a standard reference material at mmWave.
