Computer aided design of reentrant coaxial filters including coaxial excitation
Computer aided design of reentrant coaxial filters including coaxial excitation
An advanced EM based CAD tool is used for the detailed characterisation of a family of reentrant coaxial waveguide filters. The EM analysis includes the effects of tuning screws and of the input/output coaxial excitation. The software is essentially used as an efficient replacement for the traditional experimental characterisation procedure. As a result, design curves are obtained relating relevant electrical parameters to normalised structural dimensions. In addition to the theory, a four-pole filter structure has been built and tested demonstrating very good agreement between simulations and measurements.
