A study on novel broadband Ku-band spatial power divider/combiner

A novel broadband traveling-wave power divider/combiner structure with waveguide ports and microstrip probes is presented at Ku-band for the first time. Design procedure was simplified by mathematical modeling and full-wave simulations. A design of Ku-band 2-way power divider/combiner was carried out to verify the approach. Some fabrication details of conventional machining were taken into account by setting up simulations. The measured results showed a minimum overall insertion loss of 0.42dB corresponding to a combining efficiency greater than 90%, and 1dB bandwidth of 36.2%.
