ANECHOIC TEST BOXES (ATB)
ANECHOIC TEST BOXES (atb) FOR ACCURATE ANTENNA PATTERN AND
RADAR CROSS-SECTION MEASUREMENTS
 
Low cost solution to anechoic chamber.
Reflection signal (reaching test zone) down by min -30dB with respect to direct signal.
Low RCS (Plastic pipe and holding devices) stand supplied to hold transmitting antenna (generally a high gain pyramidal horn.)
The antenna under test / Radar Cross Section measurement target stand provided on a manually/ electrically operated turntable with low RCS stand.
Five-side absorber covered plywood boxes.
Special corner block absorbers used.
Suitable type optimum performing absorbers at near normal/grazing incidences of extraneous signals used.
Two types of boxes are being made. Custom tailored solution, other size boxes, anechoic chambers can be provided.
KV-ATB-X, suitable for X band and higher frequency, viz., frequency higher then 8.0 GHz Size 0.8m X 0.8m X 1.0m typical.
KV-ATB-L, suitable for 900 MHz and higher frequencies. Performance (Reflection Loss) at lower frequencies shall be deteriorated, like at 750MHz it will be-25dB only), Size 1.2m X 1.2m X 1.2m typical.
   
Suitable for Microwave and Antenna labs.
Designed in view of requirements of educational institutes.
Necessary attachment for Antenna/Microwave Trainer kits.
Necessary requirement for accurate antenna pattern/RCS Measurements.
