a chip;

a battery integrated into the chip;

wherein the chip comprises a substrate, wherein the substrate comprises a cavity having a bottom and sidewalls, and wherein an anode of the battery is disposed at least at the bottom of the cavity;

an antenna;

a first supply circuit, which is configured to supply the one or the plurality of components to be supplied by means of energy received from the antenna, and

a second supply circuit, which is configured to supply the one or the plurality of components to be supplied by means of the battery, if the energy received by the antenna does not suffice for supplying the one or the plurality of components to be supplied.

2. The radio communication processor arrangement of claim 1,

wherein the radio communication processor arrangement is a smart card or an RFID tag.

3. The radio communication processor arrangement of claim 1, further comprising:

a radio communication processor configured to process received digital signals or digital signals to be transmitted.
