The well-established calibration techniques for loop antennas have in common that either some parts of the antenna design or the field pattern of a standard field must be well known or fully theoretically describable. In this paper a pure metrological approach, circumventing these requirements is introduced and verified. It is based on a generic two port network model for loop antennas and a traceable...
Magnetic loop antennas are commonly used for investigations on magnetic fields in a frequency range up to 30 MHz. As for all antennas the antenna factor is the result of a calibration procedure. Commonly used calibration routines like the standard field, standard antenna and three antenna method will be compared to a newer approach called impedance method, first introduced by Ishii [2]. Finally a...
Consideration of the measurement environment of loop antennas is of great importance since loop antennas for low frequency magnetic fields are mostly used under near field conditions. To do this in the right and entire way, the whole measurement set-up has to be taken into account. For this application it would be of great advantage to use a contactless method. As classical calibration methods cannot...
