The proposed power divider which is designed based on Cohn topology is implemented on an RO4003C dielectric substrate which has the relative permittivity and the thickness of 3.55 and 1.524mm, respectively. Seven pairs of 1:2 power divider are used to construct the design of 1:8 power divider. Some parameters such as insertion, isolation and voltage standing wave ratio (VSWR) are used to analyze the performance of power divider in the frequency range of 2-4GHz. The result shows that the 1: 2 power divider has the values of insertion loss, isolation and VSWR of greater than 3.08dB, greater than 24dB, and less than 1.1, respectively. Meanwhile, the 1:8 power divider has the insertion value of greater than 9.26dB, isolation value of greater than 23dB, and VSWR value of less than 1.5. The characterization result has shown an adequate performance for S-band array antenna feeding network of radar system.[/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]Array antennas,Dielectric substrates,Feeding networks,Frequency ranges,Isolation value,Power divider,Relative permittivity,Voltage standing wave ratio (VSWR)[/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]Array antenna,Cohn topology,feeding network,power divider,radar system[/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 postgraduate team research program (Penelitian Tim Pasca Sarjana) FY2017 from the Ministry of Research, Technology and Higher Education, the Republic of Indonesia.[/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/ICCEREC.2017.8226695[/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]
