The evaluation of ridge profile is carried out based on the Gaussian function. The characterization is performed by varying variables in the function, namely gap between the ridge profiles, width of the horn aperture, length of the antenna horn, and maximum factor of the Gaussian function. The beamwidth and sidelobe level are the observed terms to represent the performance of proposed QRHA. It is found that the parameters significantly influence the performance of QRHA are width of the horn aperture and maximum of the Gaussian function. It can be inferred that the narrower antenna beamwidth is obtained in accordance with increasing both of parameters. While in term of sidelobe level, the optimum performances are achieved by reducing aperture of the horn and maximum of the Gaussian function.[/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]Beam widths,Gaussian functions,Quad-ridged horn antennas,Ridge profile,Sidelobe levels[/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]Beamwidth,Gaussian function,Quad-Ridged Horn Antenna (QRHA),Ridge profile,Sidelobe level[/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 Ministry of Research, Technology, and Higher Education, The Republic of Indonesia under the SAINTEK project 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/CAMA47423.2019.8959692[/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]
