Here, the DGS is applied for enhancing the passband bandwidth response, S-parameters, as well as for size miniaturization. In the design process, some parametric studies of DGS such as changing the length of DGS, width of DGS, and number of DGS slot are performed to optimize the microstrip BPF in achieving the optimum bandwidth response and S-parameters. Microstrip BPF is deployed on a 0.8mm thick FR4 epoxy dielectric substrate with the dimension of 27.4mm × 22mm. The simulation result shows that the proposed microstrip BPF has bandwidth response of 4.55GHz ranges from the frequency of 1.4GHz to 5.95GHz.[/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]Bandwidth enhancement,Design process,Dielectric substrates,Microstrip bandpass filters,Optimum bandwidths,Parametric study,Size miniaturization,Strip elements[/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]Bandwidth enhancement,defected ground structure (DGS),microstrip bandpass filter (BPF),ultra-wideband (UWB)[/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/ICWT.2017.8284135[/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]
