Innovative Near Field and Very Near Field Antenna Test Ranges: Innovative test ranges based on phaseless NFFF transformation te,Used
Delivery time: 8-12 business days (International)
Near Field Far Field (NFFF) transformation techniques (TT), based on the knowledge of amplitude of the radiated field of the antenna under test (AUT), enable a significant reduction of the complexity (and hence of the costs) of a NF test range. Phase measurement, indeed, requires sophisticated measurement chains (VNA, stable cables), high stability of the environment (humidity, temperature), high accuracy of the positioning systems. These constraints become tighter with the increasing frequency, making the test range more complex especially when dealing with the millimeter (or smaller) wavelengths. Noninvasive behavior of photonic probes for EM field sensing allows reducing the perturbation on the measurement introduced by standard metallic probes, enabling the positioning the acquisition domain in the AUT close proximity (very NF). Hence, it can improve the signaltodisturbance ratio, improve the interference immunity and reduce the acquisition time (or truncation error). This work proposes the design of an innovative, NF and VNF antenna test range, conjugating for the first time the advantages of phaseless NFFF TT with the noninvasiveness of photonic sensing of EM fields.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
