Design and Analysis of Vivaldi Antenna for Measuring Electromagnetic Compatibility

The paper presents design and characterization of a pair of Vivaldi antennas in the frequency range from 0.5 to 4 GHz. The design procedure is described in details together with analysis of the antenna current density distribution and the operating mechanism. Simulated and measured relevant results are compared and discussed. 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, so it can be considered as a suitable solution for high frequency component of the electromagnetic compatibility (EMC) measurement system currently being developed within Department of Electrical Engineering Fundamentals and Measurements at University of Zagreb, FER.
