SIW distributed amplifier: Analysis, prospects and challenges
Substrate-integrated waveguide (SIW) distributed amplifiers require complicated waveguide components which can make comprehensive full-wave simulation difficult. To better assess the amplifier, much of the waveguide componentry can be accurately represented by equivalent half-mode rectangular waveguide. In this work, spurious coupling between close proximity waveguide open-edges are shown to adversely affect performance and the challenge is to mitigate this affect.
