NeoScan systems can be used as an essential tool for characterization, test and evaluation of antennas and phased array systems. The radiation patterns of antennas and arrays are traditionally measured in anechoic chambers. 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 near-field ranges are smaller replacements for full-sized chambers.
