Abstract

Abstract: An all‐resonator based triplexer is presented using a double‐stub‐loaded resonator (DSLR) that acts as a common resonator at the junction of the three channels. The open stub DSLR has been analyzed using even and odd‐mode method to reveal the relationship between the three resonant modes. The design offers flexibility of frequency selection. The DSLR resonator is coupled with three sets of hairpin resonators to form the triplexer at 1.8, 2.1, and 2.6 GHz for mobile communication applications. The measurement results are in very good agreement with the simulations.
