1. A microwave energy delivery device for delivering energy from an energy source through a transmission line having a shielding element, the microwave energy delivery device comprising:
a microwave antenna portion located at a distal portion of the transmission line and comprising a radiating element and a shaping element, the radiating element having a distal region;
an elongate dielectric material comprising an axis mechanically coupled at a first location to a region of the radiating element and at a second location to a region of the shaping element, wherein the first location and second location are spaced apart along the axis;
where the radiating element emits a microwave field when energized by the energy source; and
where when the shaping element is in electrical contact with the shielding element and is located adjacent to the radiating element such that at least a portion of the shaping element extends along a portion of the radiating element causing the shaping element to affect the microwave field by limiting the microwave field about the microwave antenna portion.
