<p>A shaped reflecting antenna with sector coverage that, located nearby a settlement, makes possible the distribution of the signal towards users positioned in the sector of antenna coverage for a maximum distance that depends on the power of the transmitting system. The purpose of the invention is to create an antenna able to radiate energy towards various users in such fashion as to assure a signal/noise ratio independent of the distance of the user from the sending antenna. It is then an antenna with a radiation pattern constant in azimuth for an angular sector chosen on the basis of the angle of view of the zone served, and shaped in the vertical plane in such fashion as to assure a signal/noise ratio independent of the distance of the user from the sending antenna. The reflector may have a grille structure. The invention finds its use in the field of microwave and millimeter-wave antennas, with shaped reflectors, and with sector coverage. <IMAGE></p> |
