    Among all antenna payload solutions suitable to support reconfigurable and flexible broadband satellite communication missions, DRA antenna systems represent the typical candidates to fulfill these requirements. Unfortunately, periodic DRA antenna solutions are characterized by different drawbacks, mainly related to the very large array aperture dimensions needed to obtain narrow high-gain spot beams, with as consequence very high number of active radiating elements, high system complexity, high weight, difficulties in accommodation and high manufacturing costs. Another key point for future satellite telecommunication missions is to consider antenna systems able to operate simultaneously at both receive and transmit bands using the same antenna aperture. The transmit/receive DRA antenna characterized by the same aperture for satellite applications presents many difficulties at higher frequency as the Ka Band, due to the operative frequency band considering a frequency ratio 1.5 between transmit and receive. In this respect, the selections of the adequate radiating element inter-spacing and the antenna aperture size have to consider both transmit and receive performances. A very interesting antenna solution potentially suitable to overcome all these drawbacks is represented by an Imaging antenna architecture fed by two small active phased arrays, one for TX and one for RX. Moreover, in order to minimize the number of radiating elements, satisfying pattern requirements in terms of sidelobe and isolation levels, aperiodic/sparse array configurations have been considered to feed the Imaging antenna system.

  • E3000 Mechanical Platform Strategic Improvements

    The programme comprised four elements, the first to develop a range of three E3000 SXL Satellite Platforms (featuring CPS MkIII), the second was a combination of E/W radiators and TWT implementation enhancements in order to extend thermal capability, the third was a range of payload implementation improvements and the final package was to develop the products necessary to offer a E3000 100V platform into the market.

  • Advanced Particle Filters

    In the frame of European efforts for independence regarding equipment for satellite communication, this project aims to develop ITAR free 20µm bi-propellant particle filter to meet applicable requirements related to the existing European Geostationary Telecom platforms.
