MVG Launches the CXR Feed - Improving Polarization Purity of Single Reflector Compact Antenna Test Ranges
MVG (Microwave Vision Group) announces its latest innovation, the CXR feed, for accurate CATR measurement.
Paris, November 23, 2015 (Newswire.com) - Accurate testing of low cross-polar antennas in Compact Antenna Test Ranges (CATR) requires a quiet zone with high polarization purity. In the testing of electrically large antennas fitted to large platforms this requirement is often the main motivation to choose the more complex and thus expensive compensated dual reflector CATR as opposed to the simpler and cheaper single reflector CATR.
With the CXR feed, MVG has developed and validated a new plug-and-play component that performs cross-polar reduction, similarly to the second reflector in dual compensated CATR.
The CXR feed has been conceived to significantly improve the cross-polar accuracy of side/corner-fed single reflector systems but is equally suitable for dual cylindrical reflector systems.
The concept behind the CXR feed is the cancellation of the Geometrical Optics (GO) cross-polar component induced by any offset reflector by means of an innovative architecture providing conjugate field matching over a bandwidth of 1.5:1.
While maintaining all other quiet zone performance parameters, the feed provides uniform low cross-polarization levels, typically 40dB cross-polar discrimination. This is directly translated to an improvement of the uncertainty budget of the system.
The dual linear polarization of the CXR facilitates the measurement process. It shortens the feed alignment time and can greatly reduce the measurement time.
Talking about this latest development, Lars Jacob Foged, MVG’s Scientific Director explains: “High polarisation purity of the test area undoubtedly impacts measurement accuracy. This novel feed concept is a breakthrough in CATR systems as it extends their measurement capabilities beyond the traditional limitations. And this at the affordable cost of a feed replacement.”

About MICROWAVE VISION
Since its creation in 1987, The Microwave Vision Group (MVG) has developed a unique expertise in the visualization of electromagnetic waves. These waves are at the heart of our daily lives: Smartphones, computers, tablets, cars, trains and planes -- all these devices and vehicles would not work without them. Year after year, the Group develops and markets systems that allow for the visualization of these waves, while evaluating the characteristics of antennas, and helping speed up the development of products using microwave frequencies. The Group's mission is to extend this unique technology to all sectors where it will bring strong added value. Since 2012, MVG is structured around 3 departments: AMS (Antenna Measurement Systems), EMC (Electro-Magnetic Compatibility), EIC (Environmental & Industrial Control). MVG is present in 9 countries, and generates 90% of sales from exports. The Group has over 300 employees and a loyal customer base of international companies. The Group generated revenues of € 56.7 million in 2014. MVG has received the BPI "Innovative Enterprise" award.
