Abstract
This paper presents a second-order dual-band bandpass filter (BPF) with sharp selectivity, good insertion, and wide stop band. Two modified open loop resonators are coupled to achieve the dual pass band at frequencies 1 and 2 GHz. An Interdigital structure is loaded on the resonator to reduce size as well as to improve selectivity of the proposed filter. Stubs are used to remove harmonics in higher frequencies for wide stopband. The scattering parameter of filter shows insertion loss and return loss in both pass bands of the filter less than 0.4 dB and better than 10 dB, respectively. The geometry of filter is designed on Rogers_RO3010 with dielectric constant 10.2 and of thickness 1.27 mm. The performance of the proposed filter is found better and smaller in size than filters designed by simple open loop resonator. The geometry of proposed filter is planar that makes it fabrication-easy and cost-effective.
