Abstract

A fully telemetric sensor concept is presented for real-time angle and position measurement using millimeter-wave metamaterials that exhibit Fano resonant behavior. The idea is to determine the angle of rotation from the reflection signals of a millimeter-wave transceiver chip. A metamaterial geometry exhibiting Fano resonance behavior has been designed and implemented on low-cost FR4 laminates. In addition, we show numerical and experimental analysis of the sensing effect and present the implementation with a frequency-modulated continuous wave (FMCW) chip.
