At ETS‑Lindgren, our Near-Field to Far-Field (NF-FF) transformation capabilities provide accurate and efficient antenna characterization without requiring large far-field test ranges. Our NF-FF solutions allow for precise near-field data acquisition, which is then mathematically transformed into far-field results, enabling detailed analysis of antenna performance while minimizing space and environmental constraints.
Near-Field to Far-Field
Near-field antenna measurements are transformed into highly accurate far-field performance data. ETS‑Lindgren scanners enable precise characterization of radiation patterns, gain, and efficiency.
We support various near-field measurement techniques, including planar, cylindrical, and spherical scanning, to accommodate different antenna types and applications. These methodologies ensure accurate characterization of key parameters such as gain, beamwidth, polarization, and radiation patterns. By leveraging advanced probe positioning systems, high-precision RF measurement instrumentation, and sophisticated transformation algorithms, we provide reliable far-field data with excellent accuracy and repeatability.
ETS‑Lindgren’s NF-FF solutions are ideal for industries requiring high-performance antenna testing, including aerospace, defense, and wireless communications. Our systems integrate seamlessly with our comprehensive test and measurement solutions, offering automated data processing and real-time visualization tools. With our expertise in electromagnetic measurement and system integration, we deliver turnkey NF-FF solutions that help engineers optimize antenna designs and meet stringent industry standards.
