要約(英語): The contributions of this study are the proposal of a distance sensor based on magnetic resonance coupling with a novel configuration and error evaluation of the proposed sensor. Since the measuring device and their batteries are connected to the target side in conventional distance sensors based on magnetic resonance coupling, the batteries need to be changed during long-term operation. Therefore, in this paper, a distance sensor that integrates the measuring device into the transmitter side is proposed; in this sensor, external attachments or batteries on the target side are not required. In addition, the distance error in the proposed sensor is evaluated by theory and experiment. In these evaluations, the effect of the Q factor on the relation between the distance error and the distance is the main consideration. Apparently, high-Q-factor antennas can reduce the distance error for long distances but increase the error for short distances. The obtained result can be used as a guideline for designing distance sensors.
