Assignee: WPC WIRELESS POWER AND COMMUNICATION AS
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An inductive communication unit for use in two-way communication, wherein the communication unit comprises:

a transmitter coil configured to generate a first alternating magnetic field representing first information to be transmitted, and
a receiver coil configured to receive a second magnetic field representing second information to be received,

wherein the transmitter coil and the receiver coil are arranged extending in parallel in vicinity to each other and positioned overlapping each other in part to an extent that, upon exposure of the first alternating magnetic field to the receiver coil, an overlapping portion induces a first current and a non-overlapping portion induces a second current, wherein the first and the second currents are of same magnitude and opposite polarity,
wherein the transmitter coil and the receiver coil have the same size and shape, wherein the transmitter coil and the receiver coil are positioned so that, when viewed perpendicular to their extension, they are collectively forming a contour comprising a central portion constituting the overlapping portion and a peripheral portion constituting the nonoverlapping portion, wherein the peripheral portion comprises two or more branches extending symmetrical from said central portion,
wherein the peripheral portion comprises two or more pairs of branches.
