摘要： A broadband satellite antenna for producing a dual-band multiple beam coverage in transmission and reception based on an offset dual-optics configuration that includes a single main parabolic reflector, a hyperbolic sub-reflector, a first transmitting Multiple-Feed-per-Beam feed system, and a second receiving Multiple-Feed-per-Beam feed system. The sub-reflector surface is a Frequency Selective Surface configured to transmit any electromagnetic signals in the higher frequency band and to reflect any electromagnetic signals in the lower frequency band. The Multiple-Feed-per-Beam feed systems are located at the main focal point FMO and at the first sub-reflector real focal point FSreal. The eccentricity e of the hyperbolic sub-reflector depends on a ratio between a preset lower frequency fL in the lower frequency band BL and a preset higher frequency fH in the higher frequency band BH. The first transmitting Multiple-Feed-per-Beam feed system and the second receiving Multiple-Feed-per-Beam feed system are geometrical scaled versions of each other.

摘要： A radio frequency radiation module includes a beam forming network capable of applying a signal including contributions to several beams, to several channels. Each channel has a high power amplifier without redundant units, and an antenna radiating feed connected to the output of the amplifier. The beam forming network has a device for selective compensation for failure of one of the channels, increasing the power of the contribution of at least one of the signals to a beam for which the radiation is affected by the failure.

摘要： A reconfigurable zonal beam forming system for an antenna on a satellite in orbit includes, in cascade, a signal splitter applying signals of equal amplitude to each channel, first variable phase-shifters and amplifiers and a Butler matrix the outputs of which are connected via second variable phase-shifters to the radiating source elements of the antenna. Varying the phase-shifts introduced by the first and second phase-shifters reconfigures the transmitted beam optimally. A preferred variant of the system further includes variable attenuators. A control device is used to apply optimization parameters. A method of optimizing the resulting configuration uses a gradient search algorithm.

摘要： The apparatus comprises: an array of N radiating elements, subdivided into P subarrays of M elements each, each beam of a specified pattern using a plurality of elements selected from the elements of at least some of the subarrays; a common signal source; power divider means having one input and N outputs to distribute the signal delivered by the source; amplifier means for amplifying said signal; and means for selectively exciting at least some of the elements with the amplified signal at a controlled phase shift so as to obtain the radiation pattern specified for the antenna. According to the invention, the apparatus is provided, between the power divider means and the radiating elements, with: P groups of M phase shifter-and-amplifier modules placed at the output of the power divider means; and P couplers each having M inputs and M outputs, said M inputs being connected to the M corresponding outputs of the associated group of phase shifter-and-amplifier modules, and said M outputs being connected to the M elements of the associated subarray. The phase shifts of the phase shifter-and-amplifier modules are selected in such a manner as to direct the power delivered by the source to those radiating elements that contribute to the specified radiation pattern, and thus to provide distributed amplification of the signal emitted by the source while maintaining an essentially identical and constant load on each amplifier regardless of the changes made to the radiation pattern.

Advantageously, the grid of the circuit for drawing off electrostatic charge is superposed over the grid of the electrode for collecting the current generated by the photocell.

摘要： A circular polarization antenna whose radiation pattern is in the shape of a body of revolution about an axis and has a radiation minimum in the direction of this axis comprises a reflective conductive surface which is essentially in the shape of a body of revolution about the axis. A rectilinear conductive rod extends axially from a first end at the level of and isolated from the conductive surface to a second end and is connected at its first end to an excitation line. A plurality of radiating arms each have a first part extending in an essentially radial plane from the second end of the conductive rod. This first part is electrically connected at its proximal end direct to the conductive rod and is extended at its distal end by a curvilinear rod typically lying on the surface of a sphere centered at the second end and whose general direction is inclined relative to the radial plane.
