“…The SIW is miniaturized to different degrees depending on the shape and size of the CSRR, and miniaturized BPFs can be designed using the SIW structures loaded with CSRR [13] and triplexers [14] but have more radiation loss compared to SIW. In addition to waveguide-type structures, there is another commonly used planar structure, the microstrip line, [15] which is lightweight and has a more compact structure [16,17] than waveguide-type transmission lines but also has more insertion loss. When designing multiplexers with microstrip lines, [18,19] because of the requirement of inband isolation, some distance is often left between transmission lines of different frequencies to guarantee higher…”

This paper proposes a new structure based on substrate integrated defected ground structure (SIDGS), and uses this structure to construct a compact triplexer with narrow bandwidth. Compared with the previous literatures related to the triplexer, the triplexer formed by this structure has a smaller size. In addition, the structure has good scalability and can be composed of any number of multiplexers without worrying about the coupling between the slots, which has favorable design flexibility. Moreover, the method of designing a multiplexer using this structure is also given, simulated, fabricated, and measured to prove the method's effectiveness.
