Abstract: A wireless charging device (35) for charging a battery of a mobile electronic device (1). The charging device (35) includes a wireless receiver (39) and a plurality of electrodes (44, 45) that are connected to a power source. The power source is controlled by a controller (40) that is coupled to the wireless receiver (39). Whilst the wireless receiver (39) receives a wireless signal that is associated with a compatible mobile device (1) the controller (40) instructs the power source to power the electrodes (44, 45). Alternatively, the wireless signal can be indicative of the need of the mobile device (1) to be charged and the controller (40) will only power the electrodes (44, 45) if a signal indicating that the mobile device (1) needs to be charged is received. A mobile battery operated device (1) that sends an indicating signal when the battery of the device needs to be charged.

Abstract: In accordance with an example embodiment of the present invention, a multi-band antenna is configured to receive signal information at a signal frequency and electric power at an energy frequency.
