“…An SIW filter with square CSRRs has been proposed, and the characteristics of passband have been observed by varying the directions of the CSRRs [18]. CSRR has been modelled on the top surface of the SIW that provides a passband below the initial cutoff frequency of the waveguide TE 10 mode [19]. By loading CSRRs onto the SIW cavity, the SIW bandpass filters have been achieved in compact size and high selectivity [20].…”

A novel Artificial Neural Network (ANN) based two Substrate integrated waveguide (SIW) bandpass filters comprising Complementary Split Ring Resonators (CSRRs) are proposed in this paper. These CSRRs are modelled on the upper layer of the SIW cavity. A feed forward multilayer perceptron (FF-MLP) neural network is used to optimize the physical dimensions of the proposed filters. To validate the analytical results, physical prototypes of the proposed filters are fabricated, and a measurement is carried out with a Combinational Network Analyzer (Anritsu-MS2037C), and the obtained experimental results agree well with the estimated results using full wave analysis. Within the passband from 8.22 to 8.95 GHz, S 12 of the first filter shows better than −0.5 dB insertion loss (IL) and a fractional bandwidth of 8.5%, and within the passband from 8.21 to 8.73 GHz, the second filter shows IL about −0.8 dB and a fractional bandwidth of 6.1%.

“…Meander line technique compound with Minkowski fractals introduced in [4] is more complex and requires higher machining accuracy, and insertion loss of the filter proposed in [5] is large. Substrate integrated waveguide (SIW) technology can be a great choice for miniaturization [6,7]. In [7], an SIW cavity resonator is loaded with stubs on the two side edges, which allows the stub loaded cavity to operate below its resonance frequency, and the dimension is about 1.63λ g × 0.43λ g .…”

This paper proposes a novel miniaturized bandpass filter by loading a stepped-impedance resonator (SIR). Owing to the intrinsic characteristic of SIR, a third-order bandpass filter with SIR is presented, which has a size reduction of 38% compared with the conventional hairpin-line filter. On account of the electrical tape gap effect of a defected ground structure (DGS), further miniaturization is realized by introducing a pair of complementary split-ring resonator (CSRR) DGSs. Besides, frequency selectivity and out-of-band rejection can be improved by adding CSRR DGS and source-load (S-L) coupling structures, which produce two transmission zeros at two side band of passband, respectively. The results show that the passband range is 3.4-3.6 GHz, and the final size is reduced by 50.3%.
