Cancer is always the greatest threat to human health. In this work, a split-ring resonator (SRR)-based sensor was simulated for label-free detection on biomarkers in microwave. The model of biosensor was simulated by Computer Simulation Technology 2017 (CST2017) and some influences of feature parameters on resonance frequency and Q-factor were also discussed. From the simulation results, the model of sensor in our work showed ultrahigh Q-factor and sensitivity under different permittivities and also exhibited a trend of better performance when it works in higher frequency. Therefore, the SRR-based biosensor will become an important application in cancer precaution and treatment in the future.
