However, its dimension is too large for low frequency usage and commonly produces single polarization. In this paper, a dual-polarized wideband horn antenna with lower frequency extension is investigated for microwave imaging application. This design is supposed to accommodate the requirements of high resolution. The usage of ridges and dielectric inserted into the horn is proposed to produce dual polarization of the antenna and extend the bandwidth in low frequency. The characterization results show that the proposed antenna yields reflection coefficient less than -10 dB, isolation between ports below – 25 dB and sidelobe level better than -20dB at the frequency range of 2.5-14GHz for each polarization suitable for the desired application.[/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]Dual-polarizations,Dual-polarized,Frequency ranges,High resolution,Lower frequencies,Microwave imaging,Sidelobe levels,Single polarization[/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 the Ministry of Research, Technology, and Higher Education, The Republic of Indonesia under the SAINTEK 2018 project, contract number of 947/H/2018.[/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-Spring46901.2019.9017251[/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]
