The proposed pyramidal horn antenna which is designed to operate at the X-band frequency and optimized to produce circularly polarized waves is intended to be used for circularly polarized synthetic aperture radar (CP-SAR) application. The optimized antenna design is manufactured using 3D printing technology for fast prototyping time, low cost, and light weight which is very suitable for small platform of CP-SAR sensor. The performance of realized antenna has demonstrated the fractional impedance bandwidth of 26% for S11 below-10dB, the axial-ratio bandwidth of 6.2% below 3dB, and the gain achievement up to 12dBic at the desired frequency.[/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]Axial ratio bandwidth,Circularly polarized,Circularly polarized waves,Fast prototyping,Fractional impedances,SAR applications,Three dimensions,X-band frequencies[/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]3D printing technology,circular polarization,pyramidal horn antenna,synthetic aperture radar (SAR)[/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]ACKNOWLEDGMENT This research was supported in part by the RISETPro Program and SAINTEK 2018 Project from the Ministry of Research, Technology, and Higher Education, the Republic of Indonesia; the Japanese Government National Budget–Ministry of Education and Technology (MEXT) FY2015-2018 under Grant 2101; and the Chiba University Strategic Priority Research Promotion Program FY2016–FY2018.[/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/APMC47863.2020.9331626[/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]
