In this paper, analytical comparison of two power weighted functions, i.e. Blackman and Kaiser, is investigated for linear array antennas with small number of elements. Some linear array antennas with small odd and even number of elements are used to implement the weighting coefficient based on Blackman and Kaiser functions at the X-band frequency of 9.5GHz. The use of both functions is intended to have some expected radiation characteristic in terms of width of mainlobe (WML) and sidelobe level (SLL). The analysis result shows that Blackman function with small number of elements could achieve the radiation characteristics with predefined SLL of 68.8dB and inter element spacing of λ/1.5, but with some WML enhancement. This performance is better in SLL suppression than Kaiser function with predefined SLL of 68.8dB and β of 6.623.[/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]Array antennas,Inter-element spacing,Linear array antennas,Radiation characteristics,Sidelobe levels,Weighted function,Weighting coefficient,X-band frequencies[/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]Blackman function,Kaiser function,Linear array antennas,Power weighted coefficient[/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 program of Researches, Community Services, and Innovation (Program Penelitian, Pengabdian kepada Masyarakat dan Inovasi, P3MI), Institut Teknologi Bandung, Indonesia, FY2019.[/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/iWAT48004.2020.1570618533[/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]
