Abstract
A medical treatment system includes an antenna for radiating energy from a source of electromagnetic energy and including a first radiating element and a second radiating element having a conductor helically wound and coaxially positioned around the first radiating element to receive energy radiated by the first radiating element. The first and second radiating elements are positioned substantially along a longitudinal axis of the antenna with the first radiating element having a proximal end coupled to the source of electromagnetic energy. With this arrangement, energy from the electromagnetic source is efficiently conveyed from the first radiating element and then resonates the coaxially positioned and helically wound second radiating element.
