Far-field characterization of ultra-wideband antenna systems is a very challenging task. Whether you use an anechoic chamber or a conventional near-field scanning system for this task, you have to utilize different types of metallic antennas with different sizes at different frequency bands in both cases. [[NeoScan]] is inherently an ultra-wideband field measurement system. Its EO field probes have cutoff frequencies well within the terahertz region. It is primarily the RF processing back end of [[NeoScan]] that currently limits its operational bandwidth.
[[NeoScan]] field probes can measure the aperture field distribution of a wideband antenna over a very large frequency range. However, far-field radiation patterns are frequency domain data by nature. They are measured and visualized at a specified frequency. Several radiation pattern plots are typically generated at different frequency bands to characterize an ultra-wideband antenna system.
