Anteral’s Compact Antenna Test Range Feeds (CATR) are complete systems composed of antenna, polarizer (in case of circular polarization), orthomode transducer and diplexers (in case of four-port configuration). They present low VSWR, high cross-polarization (XP) cancellation and low axial ratio.
CATR systems are completely custom, choosing between linear or circular polarization and two-port or four-port configuration. Moreover, the mechanical design can be adapted to the client requirements in terms of clamping structure.
They are designed to cover the frequency range of 7 to 110 GHz in several bands with 15 dBi nominal mid-band gain, typical VSWR of 1.25 and typical axial ratio below 1 dB. Besides, custom values can be requested. These antennas are widely used in measurement applications like anechoic chambers.
