Abstract:
A printed bi-polarization antenna comprising:first, second and third superimposed substrate plates (1, 2, 3);a first metal deposit (4), situated on the external face of said first substrate plate (1) which defines at least one first radiating element (5, 6) of the dipole type, in the form of a T-shape, the horizontal bar of said at least one T-shaped first radiating element being constituted by two radiating lateral strands separated by a coupling slit;a first power supply line (7) pursuant to a first polarization, situated between said first and second substrate plates (1, 2) and supplying power to said at least one first radiating element (5, 6);a second metal deposit (8), situated on the external face of said third substrate plate (3) and defining as least one second radiating element of the dipole type (9, 10), in the form of a T-shape, the horizontal bar of said at least one T-shaped second radiating element being constituted by two radiating lateral strands separated by a coupling slit;a second lower power supply line (11) pursuant to a second polarization, situated between said second and third substrate plates (2, 3) and supplying power to said at least one second radiating element (9, 10).
