    摘要: An array antenna with reflector(s) (AR) comprises i) an array (RS) of at least two feeds (S1-S5), including a central feed (S1), arranged and positioned so as to transmit and/or receive beams (F1-F5) in chosen directions, ii) beam-forming means responsible for controlling the amplitude and phase of each of the feeds by means of amplitude/phase laws applied to their ports and providing an appropriate amplification level, in order for each feed (S1-S5) to transmit a chosen radiation pattern (forming a beam and comprising a main lobe) intended to cover a chosen zone (Z1-Z5), and iii) at least one reflector (RC) provided with a surface (SU) specifically for reflecting the beams delivered by the feeds and/or intended for the latter, and shaped tree-dimensionally so as to reflect the beam delivered by each feed (S1-S5) by spreading its energy such that it covers the chosen associated zone, that the main lobe of the radiation pattern associated with the central feed (S1) defines a primary coverage (CP) fully including each active coverage zone (ZC1,ZC2) of the antenna (AR), of chosen shape and dimensions, and that the main lobe of the radiation pattern associated with each non-central feed (S2-S5) at least partially overlaps the primary cover (CP).

    摘要: The invention relates to a radiating source for transmitting and receiving, intended to be installed on board a satellite to define a radiation pattern in a terrestrial zone, said source being intended to be disposed in or near the focal plane of a reflector associated with other sources corresponding to other terrestrial zones. The source includes a plurality of radiating apertures, each of which has an efficiency at least equal to 70%, and feed means for feeding said radiating apertures. The radiating apertures and their feed means are such that the energy radiated by all of the radiating apertures is practically limited to the corresponding reflector, at least for transmission.

    摘要: Dual polarisation antenna having low side lobes, useful in a satellite radio communication system. The antenna includes a reflector assembly (12) illuminated by a feed source (11). The reflector assembly (12) includes a front reflector (15) that reflects two electromagnetic waves orthogonally polarized and each at a different frequency, an auxiliary reflector (16) that reflects one of the orthogonally polarized electromagnetic waves, and a deflecting surface (13) that totally diffracts the orthogonally polarized electromagnetic wave that passes through the auxiliary reflector (16).
