Abstract
The authors presents the comparative analysis of a dielectric resonator (DR) based linear displacement sensor with various microwave feeding techniques. A cylindrical DR excited by common feeding techniques such as the coaxial probe feed, microstrip slot feed, microstrip line feed, and coplanar waveguide feeds is numerically investigated using ANSYS HFSS. Single-port or reflection mode sensor characteristics such as the frequency shift, displacement sensitivity, linearity, and dynamic range are found to be highly dependent on the feeding technique.
