Patent ID: 8463396

Claim:
A microwave antenna assembly for applying microwave energy therapy comprising: a proximal radiating section having an inner conductor, an outer conductor, a DC power conductor and a DC neutral conductor, each extending therethrough, the inner conductor disposed within the outer conductor and the DC power conductor and DC neutral conductor disposed radially outward from the outer conductor; a distal radiating section distal the proximal radiating section; and a junction member configured to mate the distal radiating section and proximal radiating section such that the proximal radiating section and the distal radiating sections are fixedly positioned relative to one another by a mechanically-engaging joint, the junction member further configured to include: a microwave signal amplifier configured to receive a microwave signal at a first energy level from the inner conductor and the outer conductor and configured to receive a DC power signal from the DC power conductor and the DC neutral conductor, the microwave signal amplifier further configured to amplify the microwave signal from the first energy level to at least one second energy level, the at least one second energy level being greater than the first energy level, wherein the junction member is further configured to provide the microwave signal at the second energy level to the proximal radiating section and the distal radiating section.
