Design of substrate integrated waveguide six-port for 3.2 GHz modulator

摘要

In the article, the description of the six-port implementation using SIW technology is presented. Six-port is a universal circuit used in measuring and communication technology. The first part of the paper describes the application of the six-port as a RF modulator. The second part of the article presents step by step the design of the six-port. The substrate integrate waveguides (SIW) technology is applied because its radiation in the vicinity is not as high as when using the planar structures. The simulation results of designed circuit are described in conclusion.
