This paper presents the use of DGS which takes meandered inductor (MI) shape to improve the return loss (S11) and to suppress the coupling between adjacent elements (S21) of array antenna. An FR4 epoxy dielectric substrate with the thickness of 1.6 mm is used for deploying the antenna. The MI shape slot is embedded on the groundplane at the bottom side of dielectric substrate between two elements of array antenna which are deployed on the top side. The simulated results show that values of S11 and S21 have been improved up to 4.4 dB and 1.9 dB, respectively, at the resonant frequency of 2 GHz. This is comparable with the measured results which have achievement up to 8 dB and 5 dB for S11 and S21, respectively.[/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]Array antennas,Coupling suppression,Dielectric substrates,Higher mode,Measured results,Radiation characteristics,Return losses (S11),Simulated results[/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][/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.2018.8597776[/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]
