C. Zhao, An Efficient Design Method for Band-Pass Post Filters in SIW Technology and the losses Analysis, 3rd December 2015

 

Abstract:

The characteristics of cylindrical post arrangements in the cross section of rectangular waveguides can be analyzed accurately and quickly with mode matching technique. Based on this technique, an efficient design approach for band-pass post filters in Substrate-Integrated Waveguide (SIW) technology will be introduced in this presentation. In addition, in order to investigate the various contributions of ohmic and dielectric losses affecting the performance, Six Chebyshev band-pass post filters in SIW technology are firstly designed with the introduced approach, and then simulated with a full-wave electromagnetic solver (HFSS). In particular, the influence on the insertion loss of the variations of the metal cladding and vias conductivity, the dielectric loss tangent and the thickness of the substrate is quantitatively analyzed. For validation, one prototype filter is fabricated to compare the simulations to experimental results.
