A microwave ablation system is provided. The microwave ablation system includes a power source. A microwave antenna is adapted to connect to the power source via a coaxial cable feed including an inner conductor defining a portion of a radiating section of the microwave antenna, an outer conductor and dielectric shielding. The inner conductor loops back around and toward the outer conductor of the coaxial cable feed such that a distal end of the inner conductor is operably disposed adjacent the dielectric shielding. The inner conductor includes one or more reactive components disposed thereon forming a reactively-loaded loop configuration configured to maximize delivery of microwave energy from the power source to tissue such that a desired effect to tissue is achieved. |
