The antenna which is designed to work at X-band frequency of 9.6 GHz is intended to have high gain and directivity, as well as to have good impedance matching implementable for the next generation of X-band circularly polarized (CP) synthetic aperture radar (SAR) and unmanned aerial vehicle (UAV) based microsatellite. A microstrip line is applied to feed the antenna in order to make the construction inside of antenna more compact. The structure of antenna is realized by a 3D printer machine using 1.75 mm filament polylactid acid (PLA) material and its inner surfaces are coated by copper conductive paint. The characterization results show that the fabricated pyramidal horn antenna has wideband characteristic response with the axial ratio less than 3 dB of 6.25%, the impedance bandwidth less than -10 dB of 28.75%, and the gain up to 8.7 dBiC at the frequency of 9.6 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]Circular waves,Circularly polarized,Conductive paints,Impedance bandwidths,Pyramidal horns,Three dimensions,Wideband characteristics,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][/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 Riset-Pro from the Ministry of Research, Technology, and Higher Education, the Republic of Indonesia FY2015–FY2018; the Japanese Government National Budget, Ministry of Education and Technology (MEXT) FY2015–FY2017 under Grant 2101; Chiba University Strategic Priority Research Promotion Program FY2016–FY2018; Taiwan National Space Organization (NSPO) FY2017–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/10.23919/PIERS.2018.8597894[/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]
