ABSTRACT:
There is provided an air core antenna, and method of production of same, suitable for use in implantable device, the antenna being used for telemetric communication with an outside programmer unit. The air core antenna is fabricated upon a hybrid substrate, which substrate is subsequently processed to contain electronic circuits for use in the implantable device. A groove is milled into the perimeter side walls of the antenna, and the coil wire is wound within the groove, the two ends of the coil then being attached to connector pads on the substrate. There is thus provided an antenna which is integrally incorporated into the substrate so that space requirements of the antenna are minimized, providing an antenna which has a sufficient loop area to provide the receiving and transmission characteristics required of a modern programmable implanted device. The production process of the air core antenna is suitable for use on an automated assembly line, eliminating separate mounting of an antenna, and minimizing manual interactions.
