A dual-band bandpass filter (BPF) based on a dual-mode stepped-impedance resonator (SIR) operating at 1.8/2.6 GHz is proposed. It is shown that the dual-band BPF has a smaller area (12.6 × 15 mm2), lower Insertion loss (<0.5 dB) and good return loss (>15 dB) at both passbands. In addition, two transmission zeros are created by the input and output tapping to enhance the rejection band (>30 dB). The simulations are carried out using Ansoft’s HFSS and CST-MS software.
