Anechoic Chamber

We are now offering our customers the option of measuring antenna properties in our anechoic chamber, which was designed and built for us on a turnkey basis by Albatross Projects.

If you are interested in measurements, please contact our sales department at sales@eldis.cz, we will be glad to prepare an offer for you.

The Anechoic Chamber solves the issue of testing, measuring and verifying the properties of a wide range in products of technical practice. It is mainly used for scientific and research activities in the field of measuring the parameters of antennas, antenna arrays and RF circuits.

Measuring options

Far-field measurement (cuts or 3D)
Near-fielld measurement with FIAFTA transformation to far-field (3D)
Gain measurement in swept frequency band
Setting and checking the ellipticity
Setting and measuring differential phase and amplitude
Setting and optimalization PSV and return loss
