Coaxial probes for permittivity measurement of materials
 Hub, Michal ; Urbanec, Tomáš (referee) ; Láčík, Jaroslav (advisor)
This bachelor thesis deals with the measuring complex permittivity of dielectrics using a coaxial probe with an open end in the frequency range of 300 MHz to 3 GHz. It is non-invasive measurement method can be widely used during the research of dielectrics. There are describe various approaches to coaxial probe design with respect to the expected size of complex permitivity in this work. Based on the studies available materials was proposed several probes with a focus on the method of measuring the low-loss dielectrics with help reflective plate. The probes were simulated to measure the reflectance in Design CST MICROWAVE STUDIO. Thereof can calculate the value of complex permittivity. This document lists only those probes that show good results and are prerequisite for the realization of practical measurement.
