This paper introduces a new structure of broad band coaxial waveguide transition at Ka-band. According to the existing coaxial waveguide transition theory, combined with engineering experience and the using of simulation software design and optimization, this Ka-band coaxial waveguide transition bandwidth can reach 57%, basically covering the band waveguide diameter corresponding to the main mode available band. At the same time, the structure has been improved to improve the consistency of indicators, and the methods of direct feed input – output make it more convenient in engineering applications.
