Abstract

We have presented a novel structure to design a microstrip triplexer for wireless and WiMAXapplications. To obtain a compact microstrip layout, step impedance resonators and coupled lines are used. The introduced triplexer has a compact size of 0.35?g×0.26?g, where ?g is calculated at 2.3 GHz. Also, the obtained insertion losses are 0.78 dB, 1.1 dB and 0.62 dB at 2.3 GHz, 3.2 GHz and 3.6 GHz, respectively. An equivalent LC model of the presented resonator is analyzed to tune three resonance frequencies by calculating numerical values of inductors and capacitors. Finally, the designed triplexer is simulated, fabricated and measured.
