A new approach using scalar metasurfaces for the design of linearly polarized antennas is presented. The proposed method is based on the construction of the surface impedance Zs using a technique called "phase-matching," which employs the sum of two circular polarizations in phase opposition. This process allows for the achievement of good performance of the synthesized antenna, such as the reduction of side lobe levels and the attainment of an almost symmetric main lobe regardless of the pointing direction. Numerical and measurement results are also presented., Comment: in French language, JNM, Scienceconf, Jun 2022, Limoges (Universit{\'e}), France
