The proposed planar array-Antenna which is designed to work at the frequency of 2.4GHz consists of 4×4 elements in which the inset feed method is employed to excite each antenna element. The planar array-Antenna is implemented using a 1.6 mm thick FR4 epoxy dielectric substrate and analyzed through a simulation. The simulated result of radiation characteristics for the planar array-Antenna is then validated by experimental characterization. It shows that the spiral shaped DGS incorporation yields measured radiation characteristics of the planar array-Antenna to have the bandwidth response of 140 MHz and the gain achievement of 10.47 dB at its resonant frequency. This is comparable to the simulated result which is showing the potentiality of spiral shaped DGS usage in the improvement of radiation characteristics.[/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,Dielectric substrates,Experimental characterization,Planar-array antennas,Radiation characteristics,Simulated results,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]Defected-ground-structure (DGS),inset feed,planar array-Antenna,radiation characteristic,spiral shape[/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]The work is in part supported by the Ministry of Research, Technology, and Higher Education, Indonesia for financially providing a travel grant to attend the AESPC-2018 Bhubaneswar, India.[/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/AESPC44649.2018.9033332[/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]
