There are 2 pieces of DGS pattern with a round and square pattern made on the groundplane. Meanwhile the CSRR has 2 pairs of patterns consisting of an inner ring and an outer ring. The proposed SIW BPF was designed on a 1.6mm thick FR4 epoxy dielectric substrate with the size of 45mm × 40mm. The filter is designed to have the center frequency of 6.75 GHz with the frequency range from 3 GHz to 15 GHz. The investigated parameters of filter include DGS shape, CSRR dimension, distance between vias, and via diameter. It is found that the utilization of DGS and CSRR could enhance the filter characteristics. The characterization results show that the filter with square DGS patterns has the best performance among others with S11 value of-18.44 dB, S21 value of-3.01 dB, and fractional bandwidth of 122%.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Bandpass filter (BPF),Center frequency,Dielectric substrates,Filter characteristics,Fractional bandwidths,Frequency ranges,Split ring resonator,Square patterns[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]bandpass filter (BPF),complimentary split ring resonator (CSRR),defected ground structure (DGS),substrate integrated waveguide (SIW)[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICWT47785.2019.8978219[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
