A double side of FR4 epoxy dielectric substrate with the dimension of 105mm × 130mm and the thickness of 1.6mm is used to deploy the planar array antenna. Two elements of planar array antenna are placed on the top side of dielectric substrate, while the bowtieshaped DGS is put in the groundplane at the bottom side. To reduce the amount of coupling between two elements of planar array antenna, the DGS which takes bowtie-shaped is introduced. From the results, both simulation and measurement verified that the bowtie-shaped DGS reduced the coupling at the resonance frequency of 1.955 GHz. The simulated and measured couplings could be reduced up to 0.67 dB and 2.4 dB, 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]Bow tie,Dielectric substrates,Double sides,Planar-array antennas,Resonance frequencies,Simulations and measurements[/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]bowtie-shaped,coupling,defected ground structure (DGS),planar array antenna[/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/10.1109/ISESD.2017.8253337[/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]
