Abstract This article presents a new approach in designing half‐mode substrate integrated waveguide Wilkinson power dividers based on analytical relations. Even‐ and odd‐mode analysis is used to determine the required value of the branch resistance and optimize the power divider performance, namely the output ports' isolation. In this manner, the design process for this microwave component is simplified and expedited, while an excellent correlation with full‐wave simulations is maintained. Measurements of the fabricated prototype corroborate the calculated results and demonstrate a wide output‐port isolation bandwidth of 71%. © 2010 Wiley Periodicals, Inc.
