Abstract :
The realization of a Circular Polarization Selective Surface (CPSS) exhibiting low Axial Ratio (AR) has been demonstrated experimentally in the X band, showing good agreement with the simulated response. The fabricated CPSS has been characterized using a free-space collimator system recently acquired by ESA. An AR below 1dB, which is comparatively smaller than previous results shown in the literature, has been achieved for more than 20% bandwidth.
