Patent ID: 8808281

Claim:
A microwave emitting system for delivering microwave energy comprising: a transmission line coupleable to a microwave energy source; an elongate microwave antenna having a proximal end, a distal end and an antenna axis, wherein the proximal end of the antenna is electrically coupled to the distal end of the transmission line and where the elongate microwave antenna generates a microwave field upon application of the microwave energy to the transmission line; an electrode positioned along the microwave antenna and between the proximal end and the distal end of the antenna, wherein the electrode is exposed to the microwave field emitted by the antenna and is electrically isolated from the antenna, where the electrode is coupleable to a second power supply; and a conductive wire coupled to the electrode wherein the wire is electrically isolated from the antenna and wherein a first portion of the wire exposed to the microwave field emitted by the antenna is disposed relative to the antenna axis such that every section of the first portion of the wire is non-parallel to the axis of the antenna such that arrangement of the conductive wire relative to the antenna reduces distortion of the microwave field due to the electrode.
