IMPROVEMENT AND CLINICAL APPLICATION OF MEDICAL EXTERNAL MICROWAVE RADIATOR
医用外照射微波辐射器的改进和临床应用

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.
