A novel unequal dual-band Gysel power divider

This paper presents a novel dual-band unequal Gysel power divider. To obtain the unequal property, branch lines of different characteristic impedances attached with a short-stub and an open-stub are needed. It maintains Gysel divider's high power handling advantage over Wilkinson divider. Experiment results show that good matching, isolation and power transmission can be fulfilled at dual-band simultaneously.
