All rights reserved.In this paper, a bandpass filter (BPF) composed of open split-ring resonator (OSRR) structure with square groundplane windows underneath the structure is investigated numerically and experimentally. Square groundplane windows are proposed to enhance the property of OSRR-based BPF in overcoming the passband bandwidth response. The designed BPF is constructed of 3 cascaded OSRRs connected with microstrip lines. Some parametrical study to obtain the optimum bandwidth response is carried out by changing the dimension of square groundplane window in the design process. The filter is then deployed on a 0.8mm thick FR4 Epoxy dielectric substrate with the dimension of 60mm in length and 20mm in width. From the experimental characterization, the realized OSRR-based BPF with the dimension of each square groundplane window of 12mm × 12mm shows the bandwidth response of 0.81GHz ranges from 1.75GHz 2.56GHz which is comparable with the numerical one.[/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][/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,Bandwidth response,Open splitring resonators,Square groundplane windows[/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]This work is partially supported by the Research Grant from ITB under the Program of Research and Innovation 2014.[/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/10.11591/eecsi.1.374[/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]
