Abstract:This paper introduces the principle,structure and calibration method of the technical parameters confirmationcoefficient and the evaluation process of the uncertainty of the three-loop antenna system,which is in accordance with GB/T 6113.104-2016/CISPR 16-1-4:2012 technical requirements for the antenna. At the same time,combined with the functions and technicalparameters of the three-loop antenna produced by several equipment manufacturers,the technical requirements of the measurement,measurement standards and calibration method uncertainty of the three-ring antenna are met,which can meet the technical requirementsof production,use and traceability. It can be used as a reference and technical basis for the cal ibration of three-loop antenna.
Keywords:three-loop antenna;measurement characteristics;confirmation coefficient;balun-dipole;uncertainty
