Abstract
A novel diplexer based on effective localized surface plasmons (ELSPs) resonator is proposed in this paper. The designed diplexer can simultaneously achieve easy integration, high isolation, low insertion loss (IL), and ultra-compact size. For channel I, the simulated insertion loss at a center frequency of 2.6 GHz is about 0.48 dB with a relative bandwidth of 6.58%. For channel II, the simulated insertion loss at a center frequency of 3.1 GHz is about 0.47 dB with a relative bandwidth of 6.29%. In addition, the influence of the distance between the resonators on the passband performance of the diplexer is analyzed and verified in the design with two simulation software. The simulation results of the two software verified the rationality of our design.
