摘要：In this paper, a design of hybrid microstrip diplexer is proposed for multi-band Worldwide Interoperability for Microwave Access (WiMAX) application in 2.3 and 3.5 GHz bands. The diplexer consist of a combination of two different filter designs. These filters were designed based on microstripline coupling techniques in order to obtain minimum insertion losses and achieved the desired frequency bandwidth. Therefore, a coupled open loop ring resonator was chosen for filter design in 2.3 GHz band and a folded coupled line resonator was chosen for filter design in 3.5 GHz band. Then, these filters were combined with a ring manifold matching network to be as a hybrid microstrip diplexer. As results, good agreements were achieved between simulation and measurement results in terms of insertion loss, return loss and bandwidth in 2.3 and 3.5 GHz bands.
