Abstract: The invention relates to an improved, low-height dual or multi-band antenna comprising surface transmitters, whose size varies in accordance with the frequency band to be transmitted. Said antenna is configured from a smaller surface transmitter that is located on top of a larger surface transmitter. The antenna is characterised by the following improved features: the dual or multi-band antenna is essentially configured as a one-piece punched and bent metal part; as a one-piece component, said antenna consists of at least two surface transmitters, which are electrically connected via a short-circuit; and at least the lowest surface transmitter for transmission in a lower frequency band and/or at least a surface transmitters that is lower than the surface transmitter for transmission in the highest frequency band have transmitter wings lying adjacent to their transmitter surface.

Abstract: An improved antenna array comprises at least four antennas. One antenna receives satellite signals, especially digital satellite signals. One antenna receives terrestrial signals, particularly terrestrially transmitted radio programs. One antenna is provided for the mobile radio sector. One antenna determines the geoposition. The at least four antennas are disposed in a given order such that antenna, antenna, antenna, and antenna are located one behind another from one end of the chassis.

Abstract: An improved combination antenna for receiving terrestrial, in particular vertically polarized signals, and for receiving in particular circular polarized satellite signals in accordance with the SDARS services, preferably in a 2.3 GHz band, having the following features: a monopole arrangement (7) is provided for receiving terrestrial signals, a satellite receiving antenna is provided for receiving circular polarized satellite signals, only a single monopole (7) is provided, and the satellite receiving antenna is in the form of a patch antenna (9).

Abstract: The invention concerns a space craft, such as a telecommunication geostationary satellite, comprising a body, at lease one main telecommunication antenna having a specific orientation relative to the body, at least an onmidirectional antenna having a field of view opposite to that of the main antennae and at least a radiator extensible by tilting about an axis linked to the craft body between a slowing position wherein it is pressed against the body and an extended position. Said axis is positioned substantially in the plane of one surface of the body parallel to the orientation of the omnidirectional antenna and to the surfaces or the surface bearing the main antenna. The radiator tilts at an angle close to 180 o from a position wherein it is pressed against one surface bearing a solar panel to a position wherein it extends substantially in the plane of the surface which bears it when it is slowed.
