Abstract
The invention relates to a frequency dispersive antenna. The antenna comprises at least one top part and one bottom part. The top part and the bottom part comprises radiating waveguides coupled electromagnetically by way of coupling slots to a feed waveguide. The feed waveguide of the top part of the antenna does not comprise any coupling slot over a length L. The length L is chosen so as to achieve an electric length substantially equal to the electric length of the feed guide coupled to the bottom part of the antenna. In particular, the invention applies to the pinpointing of meteorological phenomena over an angular domain greater than the natural width of an airborne antenna.
