A quasi-planar array antenna for transmitting or receiving electromagnetic waves is disclosed. The antenna comprises elements being in the form of slots that extends in H-plane from one side of the array to the other and being limited at both ends by sidewalls, and being located side-by-side to form a planar radiating aperture. The slots are fed in such a way that one or more directive beams are radiating vertically or almost vertically from said planar radiating aperture. A feeding arrangement and/or power distribution arrangement may be realized by means of parallel-plate-type waveguides, and preferably incorporating gapwave technology. |
