Analysis of S Band Substrate Integrated Waveguide Power Divider, Circulator and Coupler

摘要

The Substrate Integrated Waveguide (SIW) technology is a very promisingtechnique with which we can take the advantages of both waveguides and planartransmission lines. Therefore, in [2.1-3] GHz band various microwave componentsand devices have been designed successfully using Ansoft HFSS software. We thenproceeded to the realization of the coupler and then made measurements of thefrequency response in the range [2.1-3] GHz using a network analyzer. Thus,results of this modeling are presented, discussed and allow to integrate thesedevices in planar circuits.
