本专利所涉及的内容为微波加热材料用的微波加热器。将同轴传输线插进材料中,其一端与微波源耦合。同轴线的另一端盖上短路板,沿外导体开许多辐射孔,使用同轴线可避免空心波导中存在的要求最小尺寸的问题,利用同轴线内导体上的弹簧式定位接触装置,使用同轴线可直接与微波发生器的输出探针相耦合。 This patent relates to microwave heating materials used for microwave heaters. The coaxial transmission line is inserted into the material, one end of which is coupled to the microwave source. The other end of the coaxial cable is covered with a short-circuit board, and a plurality of radiation holes are opened along the outer conductor. The use of the coaxial cable can avoid the problem that the minimum required size of the hollow waveguide exists. By using the spring-type positioning contact device on the coaxial inner conductor, Coaxial cable can be directly coupled to the output probe of the microwave generator.
