Far Field Antenna Measurement System Without Anechoic Chamber

Far Field Antenna Measurement System’s principle of operation is based on Pulse measurement technique (Time-Domain measurements – TD). This System is applicable for most types of antennas and carries up measurements at distances R between Antenna Under Test (AUT) and measuring antenna larger then far field criteria
R=2D²⁄λ, where D – section (aperture) of antenna,
λ – wavelength.
Practically this comprises a distance from some meters to some hundreds meters depending on antenna’s size and measurement bandwidth. As main measurement instrument the Digital Sampling Converter is used. Its characteristics are optimized according to System’s parameters. The Ultrashort-Pulse Electrical Generator serves as measurement signal source.
The Systems are built for frequency ranges 6 GHz, 12 GHz, 18 GHz, 26 GHz and 40 GHz.

Except of main instruments the System can include:
– additional equipment such as transmitting and receiving reference antennas, antennas holders, pylons, positioners and rotation units, extensive fiber-optic or MW Trigger Lines, Remote Data Control Systems;
– optional equipment such as bandpass and rejection filters, MW amplifiers, phase stable cables, Pulse Generator Mainframes, Power Supplies;
– additional Software for calculation of antenna’s parameters, interpretation of measurements results and their graphical representation.
