This paper deals with the development of radiator for wireless charging application and its characterization to investigate the power transfer efficiency. The proposed radiator which takes a spiral circular shape is designed based on planar inverted-F structure and implemented on an FR4 epoxy dielectric substrate with the dimension of 240mm × 240mm and the thickness of 1.6mm. Some attempts by setting a gap separation between 2 radiators are conducted to analyze the power recipient signal affected by various gap separations yielding the power transfer efficiency. The experimental characterization shows that the realized radiator works well at the frequency of 13.75MHz with the measured reflection coefficient (S 11 ) of -14.7dB which is comparable to the simulated result. Meanwhile the average power transfer efficiency is around 34% gained from the measured results for various gap separations between 2 radiators.[/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 shape,Dielectric substrates,Experimental characterization,Inverted-F,Measured results,Power transfer efficiency,Simulated results,Wireless charging[/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]planar inverted-F structure,power transfer efficiency,spiral circular shape,wireless charging radiator[/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.2018.8605488[/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]
