The use of passive components incorporated into the structure was sometimes employed to overcome the issue of deficiency. This paper proposes wave absorber composed of multilayer dielectric substrates to enhance the absorption characteristic focused on its bandwidth performance. The proposed multilayer wave absorber is designed to work at the X-band frequency with an FR4 epoxy dielectric substrate applied for each layer. A multi-impedance concept of each layer which depends on its patch dimension is implemented to acquire the bandwidth improvement. The characteristic of proposed wave absorber is investigated through its unit cell with the dimension of 5.80 mm × 5.80 mm. The characterization result shows that the fractional bandwidth for the unit cell using square patch could increase up to 127% and 169% for the double-layer and the triple-layers, respectively, compared to the single-layer of dielectric substrate at the X-band frequency of 9.5 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]Absorption characteristics,Bandwidth performance,Dielectric substrates,Enhanced absorption,Fractional bandwidths,Multilayer dielectric substrates,Pattern structure,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 the Indonesia Endowment Fund for Education (Lembaga Pen-gelola Dana Pendidikan, LPDP-BUDI DN), the Ministry of Finance, The Republic of Indonesia.[/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-Spring46901.2019.9017538[/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]
