Kalibracja małej anteny pętlowej

The article presents examples of calibration of a small loop antenna, witch can be used to measure the magnetic component of the electromagnetic field. The source of such a field may be, for example, lightning. There are many methods of calibration a loop antenna. Two of them are presented below – using test antenna with is calibrated and with known parameters, and using a homogenous magnetic field generated inside Helmholtz coil. Measurements using the first method were carried out in the anechoic chamber of the EMC laboratory.
