Mode-matching analysis and design of substrate integrated waveguide T-junction diplexer and corner filter

The mode-matching technique is deployed in this paper in order to analyze and design a substrate integrated waveguide SIW T-junction diplexer in Ku-band. The diplexer has bandwidths of 4.12% and 3.79% at 14.55 and 15.85GHz, respectively. Also in Ku-band, an SIW corner filter is analyzed and designed with the same technique. Analytical results are compared with simulated data obtained from commercially available field solvers such as CST Microwave Studio and ANSYS HFSS. Excellent agreement between analytical and simulated data is achieved. Copyright © 2014 John Wiley & Sons, Ltd.
