Waveguide power dividers using multiple posts

A new rectangular waveguide power divider using multi- ple posts is described in this paper. The waveguide power divider is easy to fabricate and is particularly suitable for substrate-integrated waveguide (SIW) circuits. Two designed examples are presented: one is a rectangular waveguide power divider using nine posts along the E-plane and the other is a SIW waveguide power divider in which three inductive via holes are used. The measured results for the two designed power divid- ers are presented and compared with the simulated ones by Ansoft's high- frequency structure simulator, and good agreement is observed. © 2008 Wiley Periodicals, Inc.
