Abstract
The invention relates to a frequency-dispersive antenna. The antenna comprises radiating waveguides on which are formed slots. The antenna comprises at least one feed waveguide linked by coupling slots to the radiating waveguides. The variation of the pointing direction of the beam from the antenna in at least one plane is obtained by varying the frequency of the wave guided by the feed waveguide. The length of the feed waveguide between the coupling slots of two adjacent radiating waveguides is greater than the distance separating the coupling slots of these two adjacent radiating waveguides.In particular, the invention applies to an airborne antenna suited to the detection and locating of meteorological phenomena.
