An arrangement is provided for charging a charge storage device by placing the charge storage device in an RF or microwave radiation field. One or more antennas which receive the radiated RF electromagnetic field are placed on the charge storage device. Rectifiers connected to the antennas rectify the received RF electromagnetic field an produce a DC output current which is used to charge the charge storage device. The charge storage device may be a battery or a capacitor and may form an integral part of an electronic device. The same RF field that charges the charge storage device can also be employed to communicate data to transponders which may be associated with computing devices.

[ We claim:] [12.] A charging system for contactless charging a charge storage device, comprising:a source of an RF electromagnetic field radiated into free space; anda support for positioning the storage device in the free space; charge storage device comprising:an antenna adapted to receive the radiated RF electromagnetic field, the antenna being a plurality of dipole antenna elements that are combined to form at least two subsets of dipole antenna element arrays, wherein a subset is oriented at an acute or a right angle with respect to at least one other subset; anda rectifier connected to the antenna for rectifying the received RF electromagnetic field to produce a DC output current,wherein the DC output current charges the charge storage device. [14.] A method for contactless charging a charge storage device having an antenna, the method comprising:generating an RF electromagnetic field radiated into free space;exposing the antenna to the RF electromagnetic field, the antenna being a plurality of dipole antenna elements that are combined to form at least two subsets of dipole antenna element arrays, wherein a subset is oriented at an acute or a right angle with respect to at least one other subset;rectifying an RF voltage produced at the antenna by the RF electromagnetic field; andcharging the charge storage device with the rectified RF voltage.
