ABSTRACT:
The present invention consists in an antenna including at least two arrays of radiating elements disposed linearly and parallel, plane metal screens being interleaved between the arrays. According to the invention screening means, added above the radiating elements, comprise criss-cross metal filaments forming a grid and adapted always to be placed between two radiating elements.
