The dielectric material which is inserted into the QRHA is aimed to enhance the performance of QRHA, in particular, the bandwidth response with an extension into the lower operating frequency. To achieve the optimum performance, four kinds of dielectric material with different relative permittivity are utilized. The used dielectric materials are Teflon, Paraffin, Epoxy, and Duroid with the relative permittivity of 2, 2.26, 4, and 6, respectively. The characterization results show that Teflon could exhibit better performance than other dielectric materials yielding the bandwidth response of 11.5 GHz in the frequency range of 2.5 GHz to 14 GHz. Meanwhile, the bandwidth response of QRHA without dielectric insertion is 9.6 GHz in the frequency range of 4 GHz to 13.6 GHz.[/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]2.5 ghz,Dielectric insertion,Frequency ranges,Operating frequency,Optimum performance,Quad-ridged horn antennas,Relative permittivity[/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]antenna performance,bandwidth response,dielectric insertion,quad-ridged horn antenna (QRHA)[/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 research was partially supported by the Ministry of Research and Technology/National Research and Innovation Agency, the Republic of Indonesia, under the SAINTEK 2018 project, contract No. 947/H/2018.[/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/ICRAMET51080.2020.9298628[/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]
