In view of the problems in the clinical application of microwave external radiator, the needle-shaped waveguide excited radiator in the model of coaxial-waveguide transition was replaced by a tapered Archimedian spirals radiator. It improves the standing wave ratio, reduces the radiator's volume and weight and decreases the microwave leak. The result is satisfactory with clinical practices.
