Abstract

In this paper, a compact dual-channel microstrip diplexer is presented and a step impedance resonator (SIR) is used. The citation terminal is used for coupling lines and the two sets of different lengths and widths of SIR are joined for making a dual-channel diplexer. It is resonant at 1.7 GHz for GSM and 2.41 GHz for IEEE 802.11. Further benefits of the presented diplexer include minimal insertion losses (IL) of less than 0.93 dB and higher than 32 dB isolations between the ports. The primary and secondary passband group delays are less than 2.75 ns and 2.8 ns, respectively. For verification, the designed dual-diplexer is built and tested. The analysis proves that the measured and modeled results are close to each other.
