The size of the chamber, its architecture and the quality of the surrounding absorbers all affect the chamber's frequency range of operation and the accuracy of the measured results. Anechoic chamber facilities are very expensive, require a large space and are hard to operate and maintain. Compact nearConventional Near-field ranges are smaller replacements for full-sized chambers.Field Scanning Systems ==

NearThe NeoScan system provides a unique and highly superior alternative to the conventional near-field scanning systems . The NeoScan probes are by far optical and have absolutely non-metallic compositions. They are extremely small, can get very close to the most compact alternatives for antenna pattern measurementsurface of the radiating aperture, and provide ultra-wideband operation. YetDue to their non-invasive nature, conventional NeoScan probes can generate ultra-near-field scanning systems have substantial downsidesscans of the AUT. These systems involve metallic radiators that act can be used as receivers an invaluable tool for picking up diagnostic purposes. For instance, you can examine the near field inter-element coupling effects in passive and active phased arrays. The NeoScan - ANT system comes with an operational software that quickly determines the optimal distance of the antenna under test (AUT)probe from the radiating aperture for the fastest scan. Such metallic pick-up antennas cannot get close to The radiation pattern of the AUT since they would perturb its is readily computed using a rigorous near fields-to-far-field transformation without any need for eliminating artifact errors. They also limit This is due to the operational bandwidth fact that NeoScan measures the "true" near fields of the system, and their accuracy degrades significantly at lower frequency bandsAUT without any external perturbations. Sophisticated software tools are often used in conjunction  In short, with these systems to deNeoScan, you get a compact portable self-embed and minimize various errors due contained system that characterizes your antenna system from the very near fields to their specific architectures the very far fields without requiring considerable real estate. NeoScan is particularly useful for phase characterization and configurationscalibration large antenna arrays.
