Abstract
A flexible microwave ablation antenna and a microwave ablation needle including the same are disclosed. The flexible microwave ablation antenna including: a radiator for transmitting microwave for ablation; a coaxial cable for propagating the microwave for ablation generated by a microwave generator to the radiator; wherein the flexible microwave ablation antenna is bendable. Preferably, an annular composite structure is disposed around a periphery of the coaxial cable to suppress the electromagnetic wave from propagating along the coaxial cable in a reverse direction. The annular composite structure includes an annular non-metallic layer and an annular metallic layer surrounding the annular non-metallic layer. The annular metallic layer is electrically insulated from the coaxial cable.
