Basic analysis of the circuit model using relay antenna in magnetic resonance coupling position sensing system

In this paper, a novel position sensing method using relay antenna in “magnetic resonance coupling position sensing system” is proposed. Basic system is based on a novel position sensing of the target using arrayed power transmitters. In such case, the positional accuracy is significant factors to determine the capability of the system. Using “relay sensing method” it is expected that the position accuracy and a degree of freedom will be improved. The contributions of this paper are follows. Details of the basic part of the proposed method are introduced with the equivalent circuit model and the equations which form the foundation of this novel system. Experimental and simulation results are shown to validate the proposed model and theory. Applying the “relay sensing method”, it is possible to be the basic technology to realize the “highly efficient power transmission system based on position sensing and navigation for electric mobile vehicles in the space”.
