TUMA14: Resonant characterization of solid dielectrics for microwave and 5G/6G applications in the 1-220 GHz range

Presentation Abstract
Development in 5G/6G technologies require precise characterization of the complex permittivity of materials in the microwave and millimeter wave spectra, addressing various applications, e.g. microwave 5G bands, 77-GHz automotive radars, D- and G-band high-speed communication systems. Cavity and dielectric resonator devices supporting material characterization in 1-20GHz range will be presented at this seminar altogether with a family of Fabry-Perot open resonators enabling wideband measurements of solid dielectrics in the 15-220 GHz range. Measurement examples will feature PCB substrates, ultra-thin foils, automotive materials, in-plane anisotropic materials, with the measurement inaccuracy as low as <0.5% (<2%) for the dielectric constant (loss tangent)
