摘　　要：The design of single-and quad-band Bandpass Filter(BPF)topology has been presented in this paper for next-generation Internet of Things(IoT)devices.The main topology is constructed using the Split Ring Resonator(SRR),separated by the Anti-Parallel Coupled Line Structure(APCLS).A detailed analysis of APCLS has been presented,which is further used to construct the single-and quad-band BPF.The single-band BPF design consists of SRR loaded with APCLS.The developed single-band BPF displays a dual-mode response with a center frequency of 2.65 GHz and a measured fractional bandwidth of 17.17%.Moreover,a quad-band bandpass filter has been achieved using the same topology with minor modification in the SRR and APCLS electrical parameters.The developed quad-band BPF generates a dual-mode response having center frequencies of 1.2,2.4,3.5,and 4.7 GHz with the measured fractional bandwidth of 13%,26%,16%,and 5%,respectively.Two prototypes have been fabricated on the highfrequency substrate to validate the proposed topologies.Very high rejection in the stopbands region,little in-band insertion loss,and very selective passband have been measured for single-and quad-band BPFs.The measured and simulated results are well correlated.
