Spacial coaxial resonator plays an important role in spacial system. However, its multipactor efiect has not been reported so far. This paper presents a novel type of coaxial resonator structure with low multipactor risk. Compared with conventional coaxial resonator structures, the proposed structure improves the multipactor threshold of fllters nearly 3dB. Experimental results and 3D full-wave analysis show good accordance with the predicted characteristics.
