The proposed planar array-antenna which is intended to operate at the frequency of 2.4GHz is designed on an FR4 epoxy dielectric substrate with the thickness of 1.6 mm and analyzed by use of a simulation software. It consists of 4× 4 elements where the microstrip line inset feeding method is employed to excite each antenna element. The characterization results show that the use of spiral shaped DGS yields the measured radiation characteristic to achieve the gain achievement of 10.47 dBi at the resonant frequency and the -10ddB bandwidth response of 140 MHz. These results are comparable to the simulated ones which are showing the potentiality of spiral shaped DGS incorporation for the radiation characteristics improvement.[/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]Antenna element,Array antennas,Dielectric substrates,Planar-array antennas,Radiation characteristics,Simulation software,Spiral shaped,Spiral-shaped DGS[/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]Array-antenna,Defected Ground Structure (DGS),Radiation characteristic,Spiral shaped[/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 research is supported by the Ministry of Research, Technology and Higher Education of the Republic of Indonesia under the scheme of Higher Education Excellent Basic Research (Penelitian Dasar Unggulan Perguruan Tinggi, PDUPT) FY2019.[/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/CAMA47423.2019.8959551[/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]
