Competition of noncollinearity and walkoﬀ eﬀects in angular entanglement of SPDC biphoton states is examined. The wave function in its angular representation is derived. The measure of entanglement is characterized by the width-ratio parameter R, which is the single-particle and the coincidence widths ratio. Parameter R is derived as a function of the angle between the observation plane and the optical axis plane.
