An On-Chip Bandpass Filter Using Complementary Slit-Ring-Resonator-Loaded Spoof Surface Plasmon Polaritons with a Flexible Notch-Band

In this paper, an on-chip bandpass filter with enhanced notch-band is proposed based on the artificial spoof surface plasmon polariton (SSPP) structure around 60 GHz. The shapes of the tabs are modified to incorporate complementary slit-ring resonators (CSRRs) between tabs. The passband is produced...

description In this paper, an on-chip bandpass filter with enhanced notch-band is proposed based on the artificial spoof surface plasmon polariton (SSPP) structure around 60 GHz. The shapes of the tabs are modified to incorporate complementary slit-ring resonators (CSRRs) between tabs. The passband is produced by the first higher mode of the SSPP structure. By adding CSRRs, two notch frequencies have been produced in the passband. The advantage of the proposed structure is that these two transmission zeros are almost independent of each other and they do not have much impact on the frequency of the passband. Based on the measured results, the proposed filter has an insertion loss of 2.6 dB with the bandwidth of 14.3 GHz. The return loss is better than 12 dB. The notch-band has a bandwidth of 3.3 GHz with a suppression level over 20 dB. The proposed filter can be applied in the shared millimeter waveband of 5G communication systems.
