Detecting Position of a Device by Swept Frequency of Microwave on Two-Dimensional Communication System

In this paper, we propose a method to detect the position of a device embedded with an antenna by sensing the amount of electrical power from a two-dimensional communication (2DC) sheet. The system obtains a characteristic power pattern at each position by sweeping the frequency of the microwave supplied to the 2DC sheet. Our system uses a machine learning technique to learn the accumulated power pattern data to predict the position of the device. We also evaluated the accuracy of the position detection was 79.1% when the antenna is moved at 12mm intervals.
