All rights reserved.Investigation of a wide bandwidth left-handed circularly polarized printed antenna with crescent slot is presented in this paper. The antenna is proposed to be applied for telemetry communication of GAIA II/LAPAN-Chiba satellite. Here, the satellite is categorized as 100kg class satellite including payload and featured with an L-band circularly polarized synthetic aperture radar (SAR) system. The proposed antenna is designed on an NCP220H dielectric substrate with the relative permittivity of 2.17 and the thickness of 1.6 mm. The bottom side of antenna acts as feeding line and port excitation, meanwhile the front side is set as groundplane. Furthermore, at the groundplane side it is also set a square parasitic patch as radiator element. From the characterization result, the antenna could produce fractional bandwidth of -10 dB reflection coefficient (S11) up to 101% (1.3 GHz-3.58 GHz) at the center frequency of 2.25 GHz and -3 dB bandwidth of axial ratio up to 13.7% (2.14 GHz-2.45 GHz). In addition, the gain of proposed antenna is about 5.6 dB at the center 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]Center frequency,Circularly polarized,Dielectric substrates,Fractional bandwidths,Parasitic patch,Radiator elements,Relative permittivity,Wide bandwidth[/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 research is supported in part by the Japan Science and Technology Agency (JST) Japan International Cooperation Agency (JICA) FY2010-2016; the Science and Technology Research Partnership for Sustainable Development (SATREPS); the European Space Agency (ESA) Earth Observation Category 1 under Grant 6613; the 4th Japan Aerospace Exploration Agency (JAXA) ALOS Research Announcement under Grant 1024; the 6th JAXA ALOS Research Announcement under Grant 3170; the Japanese Government National Budget Ministry of Education and Technology (MEXT) FY2015-2017 under Grant 2101; the Chiba University Strategic Priority Research Promotion Program FY2016-FY2018; the Taiwan National Space Organization (NSPO) under Grant NSPIO-S-105096; and the Indonesian National Institute of Aeronautics and Space (LAPAN).[/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/PIERS.2017.8261900[/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]
