Abstract:
An efficient design technique for Substrate Integrated Waveguide (SIW) power dividers for applications in SIW antenna feed networks is presented. The analysis and optimization procedure employs mode-matching techniques using square via holes. A simple square-to-circular via hole conversion produces the final power dividers with only very little performance discrepancy between the components with square and circular via holes. Five power divider designs for K-band applications, ranging from two-way to four-way dividers, are presented and validated by commercial field solvers. Good agreement with measurements is demonstrated for a Ka-band two-way divider.
