“…Some researchers have taken on the challenge of simulating standing waves on a 2D sheet without actually measuring the electrical power on the sheet [29]. However, the actual power map is rarely the same as that generated in the simulation, as it is difficult to perfectly simulate the microwave reflected at the edge of the sheet.…”

We propose a system of detecting the position of a device embedded with an antenna by sensing the 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 detect the position of a device. The position-detection accuracy of our system was 79.1% when the antenna was moved in 12 mm intervals. In addition to detecting the position of a device, we also estimated the direction.
