    Ceramic materials for microwave systems often show versatile profiles, such as cylindrical and cubic shapes with centimeter sizes. The measurement of such samples thus becomes a challenge. In this paper, a dual-band dielectric sensor based on the complementary split-ring resonators was developed, and a measurement method to characterize the samples with different shapes and sizes was proposed. The resonator creates two operation frequency ranges, which are in wireless communication bands. In each range, numerical simulation was conducted to build the fitting models for each sample. The measurement was conducted to verify the numerical models and the measurement accuracy. The results indicate that the measured accuracy can be as high as 3.5%. Such a measurement method in association with the proposed sensor is competent for dielectric measurement for ceramic of versatile profile, indicating a sample adaptive capability. The novelty of this work lies in its capability of measurement of various samples in a centimeter scale without modifying either the sensor or the material under test (MUT). In addition, a dual-band operation is also a feature of this work, and the discrepancy between the two bands is less than 5%.
