Advances in Instrumentation and Positioners for Millimeter-Wave Antenna Measurements
Authors: Bert Schlüper and Patrick Pelland
Applications using millimeter-wave antennas have seen a strong growth in recent years. Examples are wireless HDTV, automotive radar, imaging and space communications. NSI has delivered dozens of antenna measurement systems operating at mm-wave frequencies. These are all based on standard mm-wave modules from vendors such as OML, Rohde & Schwarz and Virginia Diodes. This paper will present considerations for implementation of these systems, including providing the correct power levels, and interoperability with coaxial solutions. Many new mm-wave applications employ low to medium gain antennas that are more suited to spherical near-field and far-field measurement geometries. NSI has developed solutions to meet these needs.
