Abstract

A novel four-way substrate integrated waveguide (SIW) filtering power divider (FPD) with in-phase and out-of-phase characteristics and a large power division ratio (PDR) is presented in this work. The frequency selection and power division functions are effectively realized by employing SIW resonators at the bottom layer and at microstrip sections at the top layer, respectively. Four microstrip lines coupled with SIW cavity through a slotline realize in-phase and two out-of-phase output characteristics and a large PDR of 7:1. To verify the design method, a four-way prototype with PDR of 7:7:1:1 is designed, fabricated, and measured. Results exhibit good filtering performance, large power division ratio, and in-phase and out-of-phase characteristics.
