Position Estimation Using Phase Difference of Electrode Array for Two-Dimensional(2D) Communication System : Two-dimensional (2D) communication is a novel communication technolo which uses a sheet of special structure that allows a physical surface to propag radio signals, and a coupler that is used to input / output radio signal. Furthermore, 2D communication technology can be applied for energy transmission by using hi power carrier waves, which can easily allocate a lot of sensors on the two dimensio sheet, and gather data from each node with high throughput. In this report, a position estimation method that uses the phase difference input electrodes upon receiving pilot signal from device is proposed. The propo method is described and evaluated by measuring the phase and power level of p signal, in which reflection does not occur. The accurate position information devices can be applied to various location-specific multimedia applications in the communication system. These applications have a very high possibility that peo can explore interesting spots or items in more detail. It makes people have m comfortable lives.
