“…Among them, multiport waveguide junctions are key building blocks of many passive components. They play an increasingly important role in the design of a great variety of microwave and millimeter-wave devices, such as power dividers/combiners [Chu et al, 2014;Xu et al, 2015;Cano et al, 2016], directional couplers [Leal-Sevillano et al, 2013], E-plane T-junctions [Berdnik et al, 2015;Helszajn, 2016], double-ridge waveguide power dividers [Ruiz et al, 2015], waveguide bends, and magic-T junctions [San-Blas et al, 2007;Kamandi et al, 2015]. Low-cost manufacturing techniques, such as milling, do usually have a negative impact on the overall electrical performance of the fabricated device, due to the introduction of rounded corners in the cross section of the waveguide ports of the considered component [Cogollos et al, 2003a].…”

In this work, a full‐wave tool for the accurate analysis and design of compensated E‐plane multiport junctions is proposed. The implemented tool is capable of evaluating the undesired effects related to the use of low‐cost manufacturing techniques, which are mostly due to the introduction of rounded corners in the cross section of the rectangular waveguides of the device. The obtained results show that, although stringent mechanical effects are imposed, it is possible to compensate for the impact of the cited low‐cost manufacturing techniques by redesigning the matching elements considered in the original device. Several new designs concerning a great variety of E‐plane components (such as right‐angled bends, T‐junctions and magic‐Ts) are presented, and useful design guidelines are provided. The implemented tool, which is mainly based on the boundary integral‐resonant mode expansion technique, has been successfully validated by comparing the obtained results to simulated data provided by a commercial software based on the finite element method.
