“…For example, the possibility of printing dielectric structures either with complex shapes or with geometrically controlled e.m. properties was investigated for the realization of radar sensors, antennas, graded-index lenses, etc. [ 13 , 14 , 15 , 16 ]. Moreover, printed conductive materials were under study for high-frequency flexible sensing applications, guiding structures, antennas, etc.…”

The spread of additive manufacturing techniques in the prototyping and realization of high-frequency applications renewed the interest in the characterization of the electromagnetic properties of both dielectric and conductive materials, as well as the design of new versatile measurement techniques. In this framework, a new configuration of a dielectric-loaded resonator is presented. Its optimization, realization, and use are presented. A measurement repeatability of about one order of magnitude lower than the commonly found values (10−3 on the Q-factor and 15×10−6 on the resonance frequency, given in terms of the relative standard deviations of repeated measurements) was reached thanks to the design of a closed resonator in which the samples can be loaded without disassembling the whole measurement fixture. The uncertainty levels, the ease of use, and the versatility of the realized system make its use of potential interest in numerous scenarios.
