Near field retrieval from far field using PDFT

2008

A new algorithm is applied for obtaining the near field form far field measurements. It is not only the simple DFT applied to the spectrum, but also a newer algorithm, called PDFT, which makes use of the information in the transformed domain. Its main advantage is that the resolution obtained is better than with DFT, since more information about the antenna is used. Furthermore, no iterations are applied and the best approximation in the way of minimum weighted norm is achieved.

Detection of defective elements in an X band array antenna from its near field measurements

2007

An algorithm has been used to detect defective elements errors in array antennas. It has been applied to an X band slot array antenna and good results have been obtained. These have enabled the detection of errors in the manufacture process. We have used spherical near field measurements of the radiated field of the antenna. Then, once the equivalent currents are be obtained, an analysis of these results will be made in order to detect possible mistakes.
