This paper proposes separated circular capacitive couplers for drone. The primary side consists of circular and ring-shaped plates, and the primary and secondary sides are symmetrical. The proposed coupler structure is vertically aligned to maintain a constant mutual capacitance under rotational misalignment conditions, and it increase mutual capacitance by reducing the parasitic capacitance. In the LC compensation circuit, the relationship between mutual capacitance and system efficiency was analyzed through an equation. The mutual capacitance was compared through simulation and measurements. Coupling capacitances between each of two plates was measured using a vector network analyzer. The proposed coupler structure is designed using 3D finite element analysis (FEA) tool and verified through experiments.
