| Sumario: | The present TFM deals with the design, fabrication and experimental validation of a system for characterizing dielectric materials using substrate integrated coaxial sensors. In order to obtain a highly compact implementation, multi-layer ceramic materials in LTCC technology will be used for developing the sensor. It will consists on a capacitively-loaded coaxial resonator with an small open cavity for introducing the material under test. Thus, by obtaining the reflection coefficient of the one-port resonator it is possible to determine the resonant frequency and therefore the real part of the material permittivity. In order to perform this measurement, several RF circuits for signal generation, transmitted/reflected signal separation, as well as supply and control electronics must be developed. The TFM can be divided in the following phases: -Study of the state-of-the-art. -Analysis of substrate integrated coaxial resonators and design of an S-band coaxial sensor. -Study of correlation between resonant frequency and effective permittivity of the material. -Design of a one-port reflectometry system including source signal generation, RF circuitry and control electronics. -Manufacturing and assembly of the developed module. -Experimental validation. |
