Abstract :
This paper demonstrates that the reflection coefficients for the triax mesh are almost independent of the azimuthal variation of the angle of incidence but they do depend on the angle from normal incidence. It is demonstrated by an example how this can affect the cross polarisation performance for an offset reflector system operating in circular polarisation.
