“…An SIW band-pass filter having wide and sharp stop band, which differs from filters with a direct coupling between input and output has been proposed [11]. An SIW bandpass filter, modelled on a double layer dielectric substrate consisting of metallic via holes in order to realize the classical H-plane filter has been proposed [12]. Two cascaded mushroom resonators have been modelled on the SIW cavity that works as a dual band bandpass filter has been presented [13].…”

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%.
