The proposed antenna array is designed to operate at the center frequency of 1.275 GHz for L-band synthetic aperture radar (SAR) application. It is deployed on 2 layers of FR4 epoxy dielectric substrate with each layer thickness of 1.6mm. The antenna array consists of 5 circular ring shape elements on the top side of first layer dielectric substrate, while the microstrip line feeding network is on the top side of second layer. Some parametric studies are conducted to investigate the impact of varying physical parameters to its performance. The optimized antenna array which is implemented for realization has the dimension of 61.4mm × 173mm. The characterization result shows that the realized antenna array works properly at the desired frequency of 1.275GHz with the reflection coefficient (S11) value of-25.56dB and the-10dB impedance bandwidth of 30MHz. The measured-3dB beamwidth in E-plane is 103° and 52° for θ = 0° and φ =90°, respectively, while in H-plane for θ = 90° is 96°.[/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]Dielectric substrates,Impedance bandwidths,L-band,L-band synthetic aperture radars,Microstrip-line feeding,Parametric study,Physical parameters,Proximity coupled[/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]differentially proximity coupled,L-band,ring printed antenna array,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]This work is partially supported by the postgraduate team research program (Penelitian Tim Pasca Sarjana) from the Ministry of Research, Technology and Higher Education, the Republic of Indonesia 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/10.1109/TSSA.2018.8708825[/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]
