Summary:
The use of probe array is a well-established technology for spherical near field systems offering all the possibilities and accuracies of traditional single probe testing at a much faster speed [1-4]. The current frequency ranges for probe arrays are from 75MHz to 18GHz. Recently the problem of exhaustive testing of the high number of multi beam antennas embarked on future satellite systems has received considerable attention. Based on conventional measurements techniques this testing would lead to unacceptable cost and duration. Solutions based on "hybrid technology" taking full advantage of fast probe array technology on large mechanical scanners can drastically reduce the measurement time compared to conventional single probe test systems. This paper discusses the testing of a dual technology T-planar near-field system in Intespace in Toulouse.
