Popis:	In this paper we present an effortless method to transform a standard-gain waveguide horn antenna into a circular polarized rectangular gain horn antenna. For this, a bar-rod separator is inserted into the horn’s mouth. By modifying only three different design parameters, the S11 reflection coefficient and axial ratio frequency response can be tuned. The method has been simulated and verified on 3D-printed models in the 77 GHz automotive radar band.
