Claim Text:
1. A multi-mode communication system for a mobile phone, comprising: a plurality of antennas; a plurality of switches; a plurality of matching networks; a plurality of near field devices, each near field device coupled to a respective one of said antennas via one of said switches positioned in a path between said near field device and its respective antenna such that, when the switch is closed, it connects said near field device to its respective antenna, and such that, when the switch is open, said near field device is disconnected from its respective antenna; one of said plurality of matching networks positioned in the path between each said near field device and its respective antenna, each said near field device and its associated matching network operative to either load modulate its respective antenna or generate an active magnetic field via its respective antenna; a controller for separately controlling the switched state of each said switch such that one or more of said near field devices are selectively coupled to their respective antennas; and a voltage generator for generating a voltage from one of said antennas by magnetic induction from a magnetic field when said field is being generated by an external device, to provide sufficient power to enable at least one of said switches to connect its associated near field device to its respective said antenna, and wherein one of said near field devices is a secure element.
