The antenna is designed to work at Long Term Evolution (LTE) frequency band of 900 MHz for radio frequency (RF) energy harvesting application. A ring-shaped planar printed antenna is applied as a main part of configuration to resonate at the frequency of 900 MHz. Meanwhile another structure of S letter or S-shaped is incorporated into inside of the ring to suppress the higher order mode of resonant frequency naturally generated by the ring-shaped structure. The proposed antenna is then deployed on an FR4 epoxy dielectric substrate with the thickness of 1.6 mm. From the characterization result, it shows that the proposed antenna has a good suppression for higher order mode with the -10 dB impedance bandwidth of around 250 MHz and the resonant frequency of 900 MHz satisfying the bandwidth requirement of desired 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=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Bandwidth requirement,Dielectric substrates,Higher-order modes,Impedance bandwidths,Planar-printed antenna,Radio-frequency energy harvesting,Ring shaped structures,S-shaped[/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][/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]This work is partially supported by the grant of research program from Institut Teknologi Bandung, Indonesia, FY2018.[/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/10.23919/PIERS.2018.8597995[/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]
