Abstract :
This paper describes a new facility for rapid near-field measurement in cylindrical coordinates. This facility is hardware and software optimized and allows quasi-real time measurements on large antennas in a frequency range extending from 2 to 10 GHz. By comparison to classical near-field (NF) techniques, the time gain factor is about 100 to 1000. Such a rapidity makes now NF approach still much more attractive. Three different examples have been selected to illustrate the capabilities of such a rapid NF facility.
