Calibration of Vivaldi Antenna for EMC Measurements

The paper presents design and characterization of coaxially fed Vivaldi antenna in the frequency range from 0.5 to 4 GHz. The antennas are intended to be used for electromagnetic field measurements over wide frequency range (by which several narrow-band antennas can be replaced). It is shown that antenna exhibits stable characteristics and is relatively low-cost, while the obtained antenna factor is in line with requirements for measurements in the field of electromagnetic compatibility (EMC).
