The present invention relates to an antenna able to cover two opposite angular sectors comprising:
first and second excited elements (10,11) each able to radiate a signal beam at a predetermined frequency,at least two reflector elements (20,21,22,23), called first and second reflector elements, able to reflect said beams in opposite directions.;According to the invention, said first and second excited elements (10,11) and said at least two reflector elements (20,21,22,23) are aligned, said reflector elements being disposed between said first and second excited elements. At least two reflector elements from among said at least two reflector elements (20,21,22,23) are connected together electrically by a first transmission line (30) of predetermined length so that the reflector elements connected together participate jointly in reflecting the beams in the two opposite directions. |

1. Antenna for radiating in two different angular sectors, the antenna comprising:
first and second active elements each active element being arranged to radiate a signal beam towards a respective angular sector, the angular sectors being in different directions from the antenna with respect to one another and, a plurality of reflector elements, each reflector being configured to reflect signal beams radiated from at least one of the active elements outwards from the antenna towards one of the angular sectors, wherein said plurality of reflector elements are disposed between said first and second active elements, and at least two reflector elements, from among said plurality of reflector elements, reflecting in different directions to one another being electrically coupled by a first transmission line of a length such that their reflected radiation is in phase. |
