Abstract :
Theoretical and experimental studies are made on calibration of EMI biconical antennas and log-periodic dipole array antennas. The method of calibration treated in this paper is the Standard Antenna Method. The errors in the calibration are categorized into two groups, one originated from the theoretical background of the calibration method and the other related to practical calibration measurements. The present paper gives the fundamental formula for the Standard Antenna Method in order to study the former group of errors. The most important error sources are found to be the nonuniformity of the field in which an antenna under calibration is immersed. In addition, serious errors are caused by the close coupling between a transmit antenna and a standard tuned dipole antenna. Based on these investigations, appropriate antenna arrangements are proposed for this calibration method
