The room conditions that allow the test results to be unsuitable can be caused by external interference or reflections from electromagnetic waves. RF anechoic chamber of sufficient size can solve this problem, so that it reflects the true characteristics of the antenna being measured. However, the very high price for the procurement of the RF anechoic chamber facilities is the reason why not all educational laboratories have them. The Radio and Microwave Telecommunication Laboratory (LTRGM) designed and implemented an RF anechoic chamber with dimensions of 6.1 meters long, 4.88 meters wide and 4.27 meters high, using CRAM SFC and C-RAM Cornerblok absorbers. From the design specifications and implementation of the materials used, an RF anechoic chamber is built with a frequency range that can be measured between 1GHz – 40GHz, which can be used for satellite applications (27.5GHz, 31 GHz), cellular terrestrial networks (28GHz, 38GHz), network routing (23GHz , 3GHz), short-range radar (24 – 24.5GHz), and the maximum dimensions of the RF device tested are 50cm2.[/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]Design specification,Educational laboratory,External interference,Far field calculations,Microwave telecommunication,Satellite applications,Telecommunication engineering,Terrestrial networks[/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]Absorber,Antenna measurement,Electromagnetic waves,RF anechoic chamber[/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/TSSA51342.2020.9310852[/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]
