Compact antenna test range

A precision reflector turns a feed's spherical wave into a plane wave, so you get far-field conditions inside a room instead of on an outdoor range.

What it does

The Compact Antenna Test Range (CATR) simulates far-field conditions in a compact indoor space. Precision-designed reflectors create a plane wave, so antennas can be measured accurately without a large outdoor range.

WiSPEC specializes in rolled-edge reflectors. The edge treatment significantly reduces diffraction and improves quiet-zone quality across the whole operating frequency range.

Our CATR systems serve satellite communications, aerospace, defense and other applications that need high-precision antenna characterization.
