A device for providing an implantable lead with wireless energy, the device including: a housing configured for implantation in a patient's body； one or more non-inductive antennas substantially enclosed within the housing and configured to receive electromagnetic energy radiated from a source located outside of the patient's body； electronic circuitry coupled to each of the one or more non-inductive antennas and configured to extract electric power and excitation waveforms from the radiated electromagnetic energy as received by the one or more non-inductive antennas； and one or more connection pads substantially enclosed within the housing, wherein the connection pads are configured to couple with one or more electrodes in the implantable lead and form an electric connection over which the connection pads provide the extracted excitation waveforms from the electronic circuit to the electrodes in the implantable lead, the implantable lead being separate from the device.
