Abstract: A method and system for providing near real-time IP streaming services to a plurality of mobile terminals, each installed on a corresponding vehicle and each comprising a delay buffer. Interruptions due to artificial or natural obstacles are such to determine missing data in the delay buffer. The method and system address the management by the service control center of the transmission of the buffers refilling data to the mobile terminals with the aim of reducing the allocation of resources and service operational costs.

Abstract: Dual reflector offset mechanical pointing low profile telecommunication antenna, to be used above all on vehicles, even high-speed ones. Its reduced physical dimensions facilitate its use, with respect to the known solutions, as it allows its connecting to the receiving system, such as a satellite, though installed on a train or on an aircraft. The invention lies within the technical field of telecommunications and the applicative field of stationary, movable antennas of reduced dimensions, and accordingly within that of telecommunications in general. The original dual reflector antenna is obtained from a second-order polynomial that configurates it in the Cartesian space XYZ.

It may be used for radar applications. Compared to the current state-of-the-art, it combines mechanical and electronic scanning devices in a single system. Technical field of electronic systems and radar telecommunications included. Field of application: production of telecommunications systems.

Abstract: Shaped beam antenna, with single or double reflector, gridded or non-gridded, the shaped beams, which can rotate the polarisation, independent of the polarisation of the feed cluster, for use preferably aboard satellites and in micro-wave antennas. The antenna includes a reflector (1), one or more polarisers (2), (2a), one or more feed clusters (3), (3a) , microwave circuits (4), (4a) to set-up the BFN, input port (5), (5a), and connections (C) and (C1).

Abstract: Multiple shaped-beam or scanned beams reflector or lens antenna configured so as to have the radiating elements outside the focal plane (imaging) with improved characteristics in terms of gain and coverage area. Said antenna (FIG. 1) essentially consists of a reflector or a lens (1), a certain number of radiators (3) positioned outside the focal plane, a Beam Forming Network (BFN). It classifies in the technical field of multiple shaped-beam antennae and is applicable to radars, telecommunications in general and to space telecommunications in particular. Its most significant advantage consists in its use as transmitter antenna since in it the electric performance/complexity ratio is improved.

Abstract: A multishaped beam direct radiating array antenna has a network on which high power beam forming sub-networks are disposed. The network is interposed between radiating elements and RF power amplifiers. This antenna is in addition constituted with a traditional network in which power combiners, phase shifters and inter-connection lines are provided. The most significant feature is that, with the help of the high power beam forming network, the correct amplitude and phase values, at the radiating element level, may be achieved without differentiating the RF power amplifier output levels, thus keeping its efficiency as high as possible. One of the advantages this configuration presents is the possibility to utilize only one antenna in comparison of the previous techniques in which the same results were obtained utilizing many radiating panels.
