Abstract
An antenna (18) for microwave tumor ablation provides coaxial antenna conductors (34, 36) surrounded by an insulated sleeve (50) of length and size promoting destructive interference of axial microwave energy passing inside and outside of the sleeve (50) to limit the tail of SAR power toward the skin (46).
