Abstract

This paper presents a technique for reduction the acquisition time in the measurement of antennas in spherical near field systems using multifrequency on-the-fly acquisitions. When these acquisitions are performed, a shift in the pattern is performed. This shift appears in polarization when the scan is in roll axis, or in pointing direction when the scan is azimuth or elevation axis. In any case, this shift has to be corrected in order to compensate the different trigger time for each frequency point. This paper presents a technique for compensating this rotation in spherical near field system, by rotation of the radiation pattern in the scan axis through an easy calculation of the that shift.
