Abstract
The invention relates to a traveling-wave antenna array comprising a feed network,a radiating structurecomprising at least four elongated grid antenna sub-arrays arranged side-by-side and parallel to each other so as to form a two-dimensional antenna array,and a plurality of interface elements coupled to the grid antenna sub-arrays and to the waveguide feed network for exciting each of the grid antenna sub-arrays. According to the invention the feed network comprises a waveguide network which is at least partly arranged below the radiating structure, and there are at least two of said interface elements for each of the elongated grid antenna sub-arrays for exciting the sub-arrays simultaneously at least two points. The invention allows for high directivity and high gain to be achieved in a millimetre-wave antenna array.
