Abstract
The existing calibration methods of EMI antenna have to use three antennas. Even standard antenna method replacing the standard antenna by the calibrated antenna needs a common transmitting antenna. In this paper, a simple calibration method which uses only two antennas is discussed. The method requires a information for electric fields at receiving location. Standard antennas knowing antenna factors can determine such electric fields. Calculable standard dipole antenna has theoretical antenna factors and site insertion losses calculated by Numerical Electromagnetic Code in free space or in open area test site with infinite perfect conducting plane. Formula of new calibration method using the standard antenna are derived. Antenna factors measured by new method in open area test site of National Radio Research Agency (NRRA) are compared to the theoretical values. The results show good agreements within 0.09 dB from 30 MHz to 1 GHz.
