Abstract
We propose a design of a compact dual-bandpass microstrip filter (DBPF) for the GSM (1.8 GHz) and WiMAX (3.4 GHz) application using asymmetric SIRs. The presented filter has very low insertion loss (S21) and high selectivity for the desired band. Appearance of transmission zeroes near the edges of passband in the proposed design guarantees sharp cut off frequency and improves the selectivity of proposed band pass filter with fractional bandwidth (FBW) of 10 and 7.08 %.The proposed filter has low insertion losses, (S21) −0.24 and 0.14 dB and the return losses, (S11) −14.71 dB and −25.01 dB for the center frequencies 1.8 GHz and 3.4 GHz, respectively.
