This paper focus on the generation of calibration tables for direction finding antennas using FEKO. Indeed, calibration table realization for direction finding antennas is generally a very long and complex manipulation, depending on angle’s precision and number of frequencies. Moreover, in some cases, like direction finding antenna on complex carriers (boat, aircraft, helicopter…), it can be a very complex and expensive manipulation. In the case of an interferometer, this study compares differential phases obtained from simulations with FEKO and differential phases measured on a direction finding antenna in the frequency band [20 – 1000] MHz. We estimate the accuracy of direction finding antennas by using a simulated calibration table instead of a measured calibration table. The results show that the simulated calibration table permits obtaining results with a great efficiency and saving thus a lot of time, which is very interesting for industrial applications.
