A waveguide-based power divider using H-plane probes short-circuited with substrate metallization patterns

A novel waveguide power divider based on a coaxial-to-waveguide transition using a H-plane probe is presented. The waveguide consists of split metal blocks and substrates which are alternately stacked. The power dividing is realized by arranging identical transitions using coaxial probes short-circuited with metal patterns on the substrate. The advantages of this structure are small footprint, low insertion loss, simple fabrication, and ease of design. A design method of the proposed power divider is described. The fabricated eight-way power divider shows excellent performances at X-band.
