750 MHz-40 000 MHz A novel CATR feed concept to significantly improve the cross-polar performance of any uncompensated CATR systems, such as side/corner-fed single reflector systems.
Provides wideband dual-polarized conjugate field matching, effectively cancelling the Geometrical Optics (GO) cross-polar component induced by the offset reflector of any single reflector CATR configuration.
SOLUTION FOR • Cross-polar reduction in uncompensated CATR systems (side/corner-fed single reflector, dual cylindrical reflector)
TECHNICAL PERFORMANCE
Dual linear polarization with high polarization purity and isolation
Symmetric radiation pattern with high cross-polar performance
Stable amplitude taper with frequency
Optimized reflector edge and chamber illumination
Low return loss / VSWR
DESIGN
Patented Ortho-mode Junction with end-launch coaxial feeding
Reconfigurable feeding network optimized upon the specific CATR system geometry
Lightweight for easy handling
SURFACE TREATMENT
Alodine 1200 according to MIL-C 5541E class 3
REPEATABILITY
Stiff and robust mechanical design
Precision pins for accurate polarization alignment
