Receiving antenna with a single pointing direction for reception from several satellites of different orbiting positions

摘要

The receiving antenna with single pointing direction, for several satellites with different orbital positions, includes a multi-sector reflector including a central sector (2) and at least one outer sector (1) in an annulus about the central sector. The sectors of the reflector are formed from portions of parabaloids with different axes defining the receiving directions (D1, D2) corresponding to the various orbital positions, the sectors focusing the radiation which they receive in a common focusing zone (F). A multi-polarisation broadband source (S) is placed in the zone (F), the source being coupled to an electronic processing channel for selecting the useful signals. Application, in particular, to satellite reception in private stations. IMAGE
