A novel SIW six-port junction

摘要

Two architectures of a substrate integrated waveguide six-port junctions operating at 1.8 - 3.2 GHz were designed, simulated and compared at a center frequency of 2.45 GHz. The two structures composed of quadrature couplers were performed within an HFSS environment based on the finite element method (FEM) and printed on a Roger RT/duroid 6010. Simulation results of the SIW six-port junction without micro-strip lines showed much better performance than the other structure.
