In this paper, we presented the design of a high performance diplexer for applications of global positioning system (GPS) at 1.575GHz and wireless local area network (WLAN) at 2.4GHz, simultaneously. Two bandpass fllters (BPFs) using the modifled stepped-impedance resonators (SIRs) operated at 1.575GHz and 2.4GHz are the main blocks for the proposed diplexer. By discussing and analyzing the admittance of the even and odd modes, the transmission zero of the modifled SIR can be found, and the
