Abstract :
At certain frequencies, removal of the differential phase contribution to rain-induced microwave crosspolarisation may produce adequate crosstalk improvement in dual polarised links. It is shown that a variable polariser with a minimum of two fixed and one rotating sections can perform this operation exactly, for any rain-induced differential attenuation and phase shift.
