A method and a device for combined signal transmission or for combined signal transmission and energy transfer, in particular a portable electronic terminal. The device has at least one coil structure for producing a first electromagnetic field for energy transfer or for signal transmission, wherein the device also has at least one antenna structure for additional signal transmission. The antenna structure has a first partial structure and a second partial structure. The first partial structure is designed and/or is arranged in relation to the second partial structure in such a way that signals in a first frequency range can be received and transmitted by the antenna structure. At least the first partial structure is arranged adjacent to the at least one coil structure in a projection plane oriented perpendicular to a central axis of the coil structure.

The present disclosure relates to a charging apparatus for wirelessly charging a rechargeable electric energy store of a mobile terminal, having a housing, a primary coil device and a first control device operatively connected thereto, wherein the first control device is arranged in the housing, which has at least one air entry opening and at least one air exit opening. The housing further has a heat sink arranged in it that has an associated active air supply device, wherein the air supply device is set up to actively supply the heat sink with ambient air that can flow in, at least also through the at least one air entry opening. The heat sink has an associated temperature sensor device for sensing the temperature of the heat sink. The charging apparatus further has a second control device that has a signal connection to the temperature sensor device and is operatively coupled to the active air supply device, and that is set up to be able to activate the active air supply device as soon as and for as long as a predetermined first limit temperature of the heat sink has been reached or exceeded. Furthermore, the second control device also has a signal connection to the first control device and is set up to activate the active air supply device when the first limit temperature of the heat sink is reached or exceeded, and wireless charging of an electrical energy store of a mobile terminal is also performed.

A comb-structured shielding layer and a wireless charging transmitter thereof are provided. The wireless charging module is connected to a power source, has at least one wireless charging coil and at least one comb-structured shielding layer, and is configured to convert alternative current power from the power source to H-field electromagnetic radiations, and wirelessly charges an electronic device. The comb-structured shielding layer is disposed between the wireless charging module and the target electronic device and configured to allow the H-field electromagnetic radiations pass through. The comb-structured shielding layer includes a first area and a second area. The first area is electrically connected to a reference electric potential. The second area is electrically connected to the reference electric potential through the first area, and is configured to shield the E-field electromagnetic radiations but allow the H-field electromagnetic radiations pass through the comb-structured shielding layer.

Charging circuit for energy store of a portable electrical device has a first resonance switching circuit with a first receiver coil for receiving an alternating magnetic field which induces an electric voltage in the first coil, and an electrical component connected to a terminal of the first coil. The first coil and the further electrical component determine a resonance frequency (f0) of the first resonance switching circuit, A second resonance circuitry is also provided and has a second receiver coil and a further electrical component which determine a resonance frequency (f1, fn) of the second resonance circuitry. The resonance frequency of the second resonance circuitry is an integer multiple of the resonance frequency of the first resonance switching circuit. Receiver coils of the resonance circuitry are disposed such that during operation they are permeated by the same magnetic field lines of the alternating magnetic field.
