A single-layer linear-to-circular polarisation converter is proposed for an application to a slotted waveguide planar array. It consists of dipoles which closely couple slot arrays. The method moments clarifies the mutual coupling between and slots on waveguide. Numerical results promise use uniform parallel dipole array as existing linearly polarised measurements using in 22.0 GHz band confirm prediction; axial ratio less than 1 dB negligible insertion loss realised.
