The array of antenna consists of 4 individual antenna elements which are uniformly fed by a corporate feeding network using a λ/4 transformer impedance matching technique. The proposed antenna array which is designed to operate at frequency of 2.1GHz is numerically investigated to have an optimum performance in which some antenna parameters including return loss, voltage standing wave ratio (VSWR), working bandwidth, gain, and radiation pattern are used as performance indicators. Based on the design result, the array of antenna is then deployed on a 1.6mm thick Flame Retardant (FR) 4 Epoxy dielectric substrate with the dimension of 340mm × 100mm. From measurement result, although the measured center operating frequency is 60MHz shifted higher than the simulated one, in general it shows that the measured working bandwidth is 100MHz for VSWR less than 2 ranges from the frequency of 2.105GHz-2.215GHz and the measured gain is up to 8dB at frequency of 2.1GHz.[/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]circular sector,Dielectric substrates,Operating frequency,Optimum performance,Performance indicators,S-band radar,Transformer impedances,Voltage standing-wave ratio[/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]Antenna array,circular sector,printed antenna,S-band radar application[/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/APCC.2016.7581508[/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]
