Abstract:
1. An antenna unit for wireless communication to a multitude of wireless interfaces, the antenna unit comprising a multitude of individual antennas, each antenna comprising a coil comprising at least one winding and the individual antennas embrace the same volume in that the windings of the individual antennas are wound around the same common volume so that the windings of two arbitrary antennas cross each other when viewed in an appropriate cross-sectional plane, wherein at least one of the antenna coils is adapted for providing an inductive coupling to another device, wherein at least one other of the antenna coils is adapted for communication with another device based on electromagnetic radiation, and wherein the inductance of the antenna coil adapted for providing an inductive coupling to another device has a first inductance and the antenna coil adapted for communication with another device based on electromagnetic radiation has a second inductance, wherein the first inductance is greater than the second inductance.
