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, f_o of the proposed resonator has its first harmonics at 3.6 f_o . 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 f_o). 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.
