Abstract

In this paper, a miniaturized narrow-band Band Pass Filter (BPF) is designed using Inter-Digital Structure (IDS) loaded slowwave resonator. The IDS loaded in the resonator is able to reduce the size and shift of the spurious frequency towards higher frequency. The resonating frequency, fo of the proposed resonator has its first harmonics at 3.6 fo . The narrow-band BPF using the proposed resonator shows insertion loss less than 0.03 dB with center frequency at 1.74 GHz and with first harmonics at 3.67 GHz (3.77 fo). The proposed filter is designed on RT/Duroid substrate with dielectric constant 10.8 and thickness of 1.27 mm. The proposed resonator shows smaller size than traditional slow-wave resonator and half and quarter wavelength of transmission line resonator.
