The proposed wireless charging radiator is designed on a 1.6mm thick FR4 epoxy dielectric substrate workable at the frequency of 13.5MHz. To improve the performance of radiator, the method of planar inverted-F structure is implemented by adding a short pin at the end of radiator. This method can enhance the value of S11 wherein simulation result of the radiator without planar inverted-F structure has S11 value of -13.27dB, while the radiator with planar inverted-F structure has S11 value of -37.73dB. Beside enhancing the value of S11, the use of planar inverted-F structure is reducible the overall size of radiator by cutting off the radiator strip up to 2.617m. Therefore, by implementing planar inverted-F structure the size of radiator is 240mm × 240mm with the length of radiator strip from the probe to the short pin as far as 5.993m.[/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]Cutting-off,Dielectric substrates,Inverted-F,meandering technique,Spiral shape,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]meandering technique,Planar inverted-F structure,spiral radiator,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=”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/ICWT.2017.8284146[/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]
