Coaxial filters is widly used in microwave circuits.we research how to analysis and design coaxial filters used by a 3D full-wave field solver,HFSS.The 3D full-wave field analysis includes the effects of tuning screw,interstage coupling aperture and input/output coaxial excitation.Base on thess analysises,we work out a S-band coaxial filter aided by simulating and optimizing in HFSS.The result of the experimentation matched well with the result of simulation,and fulfiled technic targets.The coaxial filter has been used in a spaceflight project successfully.The way of combining the traditional theory with the advanced computer technology has great practical value,it can save much time and cost.
