Mapping smooth profile H-plane rectangular waveguide structures to substrate integrated waveguide technology

摘要

The guidelines for mapping rectangular waveguide structures to substrate integrated waveguide (SIW) technology are well understood for structures with straight walls. However, the mapping of a smooth profile structure from rectangular waveguide to SIW technology is not trivial and it needs to be carefully studied. A general procedure for mapping any smooth profile H-plane rectangular waveguide structure to SIW technology is proposed. A practical example is also provided and experimentally validated.
