Angular Displacement Sensor Based on Coplanar Waveguide (CPWs) Loaded with S-Shaped Golden Spiral-Tapered Split Ring Resonators (SGS-SRRs)☆

Abstract An angular displacement sensor based on coplanar waveguides (CPWs) loaded with s-shaped golden spiral-tapered split ring resonators (SGS-SRRs) is proposed in this paper. The proposed device is composed of a CPW and a SGS-SRR which was designed based on the golden ratio number and etching on double copper layer of PCB. The transmission coefficient (S21), linearity and sensitivity of the sensor were simulated and analyzed using electromagnetic models. The results show that the sensor was able to sense the rotation angle. It has a wide dynamic range, high linearity, higher sensitivity and lower cost, which is particularly suitable for use as a sensor and transducer technology in the future.
