| Abstract: | The principle of the parallel plate resonator method for measuring the dielectric properties of microwave ceramics was presented. The measurement system is discussed, in regard with its configuration, the relevant software and the operation skills. Some measured results and the advantages of this method are given. The measurement method is simple, fast and accurate though not suited for the dielectrics of the microwave ceramics exhibiting relatively larger loss. The error of the measured r is about 0.5% and that of the measured Q below 15%. |
