Receiving or transmitting high efficiency antenna of dual polarized printed radiating sources coupled with two waveguides

X band is useful to single out surface scattering especially if there is also a trend in having polarimetric S.A.R., which allows us the simultaneous acquisition of four images using receiving and transmitting antennas of dual polarizations. Polarimetric radars require the use of a double polarisations antennas having a high polarization purity and a good efficiency.
