Outline of Final Research Achievements

This research project aims to realize novel position/movement sensors based on a resonance of the emitted and reflected electromagnetic waves. This novel technique employs the frequency delta sigma modulation concept, where the movement is measured as a frequency change. As a result, it should have a wide frequency range, high resolution, and a large dynamic range. To demonstrate this concept, we integrate a wide frequency range antenna and a gain block, which can oscillate in a wide frequency range. In this research period, we demonstrated the operating principle using a prototype device consisting of a cavity resonator. Moreover, the effects of the phase noise in the oscillator on the frequency delta sigma modulation were clarified quantitatively.
