ABSTRACT:
A charging system for a portable electronic device is disclosed. The system comprises a charging station providing a magnetic field for power distribution by an alternating current source connected to a power transmission coil for providing the magnetic field, and the portable electronic device. The portable electronic device comprises a radio receiver; a charging mechanism for charging a battery of the portable electronic device; and an antenna arrangement for the radio receiver, wherein the charging mechanism comprises a first coil arranged to interact with the power transmission coil of the charging station upon charging; a rectifier connected to the first coil to receive an alternating current therefrom and to a power supply output to provide a direct current, and the antenna arrangement comprises an antenna element comprising the first coil; a resonator tuned for a frequency band in which the radio receiver is intended to receive radio transmissions; a series resonance circuit comprising a capacitor and a second coil connected in series between one terminal of the first coil and a reference voltage of the portable apparatus.
