Angle Sensor Based on Golden Spiral–Shaped Tapered Ring Resonator Using Finite Difference Time-Domain Method

Abstract:

In this paper, an angle sensor based on coplanar waveguides (CPWs) loaded with golden spiral–shaped tapered ring resonators (GS-RRs) is proposed. The E-fields and H-fields of the GS-RRs were simulated and analyzed using finite difference time-domain method (FDTD). It is shown that the proposed sensor has a high dynamic range and linearity for rotation sensing. The proposed sensor can be operated at a single fixed resonant frequency (6.32 GHz) which is inexpensive and probably for superior interest in a small scale structure using MEMS technology.
