Abstract

In this paper an attempt is made to compare the electrical performance of two microstrip band-pass filters (BPF)\ndesigned using half-wavelength (λ/2) resonator and stepped impedance resonator (SIR). Coupled resonator based design\nmethodology is adopted to design the two BPFs. The BPFs have a fractional bandwidth of around 1.9 % at 4.195 GHz. The\ncomparative study from simulated results show that the BPF based on λ/2 resonator provides better insertion loss than the one\nbased on SIR. On the other hand SIR based BPF provides better spurious signal rejection and in-addition to miniaturization.
