Design of optimal chamfered bends in Rectangular Substrate Integrated Waveguide
Recently, has emerged a new technology, substrate integrated
waveguide (SIW), it has been applied successfully to the
conception of planar compact components for the microwave and
millimeter waves applications. Our study concerns the
analysis of right bends of rectangular waveguides under SIW
technology by the HFSS code, in order to simulate different
chamfrain positions, through the analysis of the transmission
coefficient S21. In order to reduce losses of the performance, it is
usual to chamfrain the external wall of the waveguide. Thus,
through this modeling, we have confirmed the optimal position of the chamfrain. A good agreement between HFSS
simulations and reference results has been obtained.
