Numerous methods have been attempted to achieve the antenna with such characteristics. In this paper, the bandwidth enhancement of substrate integrated waveguide (SIW) antenna by incorporating slot and defected ground structure (DGS) is presented. A cross slot is applied upon the radiator of proposed SIW antenna, while a rectangular split ring slot combined with X-shape slot of DGS are incorporated at the groundplane. The proposed SIW antenna which is deployed on FR4 epoxy dielectric substrates is fed by proximity coupling method. The characterization result shows that the fractional bandwidth of 40.4% could be achieved by the proposed SIW antenna with the -10 dB bandwidth response ranges from the frequency of 1.652 GHz to 2.468 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]Bandwidth enhancement,Dielectric substrates,Fractional bandwidths,Proximity couplings,Response range,Split ring slot,Wideband antenna,Wireless communications[/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 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/10.23919/PIERS.2018.8597800[/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]
