A novel microstrip planar triplexer for multi-mode/multi-band wireless systems has been proposed in this paper. The proposed triplexer is composed of a dual-band bandpass filter (BPF), a low pass filter using microstrip stepped-impedance hairpin resonators and simple associated matching circuits. The dual-band BPF is realized by using parallel coupled microstrip lines and open-loop stepped-impedance resonators (SIR) loaded with two shunt open stubs. Compared with the conventional triplexer configuration, it only needs to design two filters.
