Accurate characterization of dielectric substrates with high sensitivity remains an important challenge in a variety industrial applications. This paper proposes innovative strategy to address this by developing and optimizing unique Complementary Multiple Concentric Split Ring Resonator (CMC-SRR). The major goal is propose sensor design increased reliability for characterization. CMC-SRR uses simple complementary SRR structures 50 Ω microstrip transmission line resonate at 17 GHz. To obtain optimal performance, analysis performed, taking into account the structure's shape, size, thickness, permittivity material under test (MUT). Fabrication specifics include use LPKF ProtoLaser on 0.51-mm-thick Rogers 5880 substrate, which allows more efficient cost-effective manufacturing. An inverse regression model created forecast unknown materials using measured resonance frequencies sample thickness. Our research yielded significant results, including relative greater than eight percent maximum prediction error less seven percent. These findings outperform current state-of-the-art resonator-based sensors described literature.
