Datasheet

CATR（Compact Antenna Test Range）

  • ・Our unique CATR system uses plane wave excitation with dielectric lenses to significantly shorten the measurement distance required by the general DFF (Direct Far Field) method for antennas with large surfaces.
  • ・Compared to CATR using metal reflectors, the use of dielectric lenses enables low cost CATR systems since surface roughness accuracy is not required compared to metal processing.

Specification

  • ・Compact CATR system using lens antennas with plane wave characteristics in a wide frequency range.
