Abstract – This paper presents an efficient method to optimise a linear-to-circular reflection polariser for non-plane wave incidence. The method is divided in two steps: first a geometrical optimisation of the cell is performed in CST and then a rotation of the cells is applied. The method is applied to a wideband dipole unit cell arranged in a cylinder parabolic surface fed by an ideal Gaussian beam. Improvements between 5 and 18 dB compared to the uniform unit cell arrangement are achieved in the two principal planes.
