Abstract

In this we paper present the design of a dual-band rat-race combiner. The desired dual-band operation is realised by adding tapped open stub to the branches of the conventional rat-race coupler. The proposed design demonstrates low and high ratios between two operating bands and provides an enhanced design flexibility. The even-odd mode analysis is used to develop the necessary design formula. The combiner is designed and manufactured on a Rogers 5870 substrate and operates at 2.45/5.8 GHz frequency bands. The measurement results revealed good performances and validated the design approach.
