The multiplication of satellite communication links has been a major trend in recent years. Thanks to the greater accessibility of earth orbits, many opportunities for new constellations deployment and services have appeared. These new services are also at the heart of issues of national and European sovereignty. In this context, the ALADDIN project will contribute to the development of high throughput satellite-based communication systems for airborne platforms, addressing in particular the « SATCOM-on-the-move » market. More precisely, the goal of ALADDIN project is to offer an innovative solution enabling significantly greater communication quality in harsh conditions, when the satellite is getting closer to the horizon. Indeed, because of strict aerodynamics, costs and stealth constraints, the airborne antennas are ideally thin and directly integrated on the fuselage. Consequently, their capacity to maintain the quality of the communication link at high elevations is drastically degraded. To this day, there is no low-profile solution on the market exhibiting remarkable scanning performance (beyond 60° in elevation). In order to address this intrinsic limitation of planar antennas, the ALADDIN project proposes to develop a specific dielectric layer, which is shaped by additive manufacturing and integrated on the inner face of the radome. This structured dielectric layer will enhance the beam scanning capability of planar antenna arrays by increasing its field of view through: the proposed patented concept consists redirecting selectively the glazing beams toward the broadside of the antenna panel in order to reduce the scanning losses and maintain the communication link and data-rates at high elevations (beyond 60°). To reach this objective, we propose in ALADDIN to work on the following points: • To demonstrate an original function of beam deviation based on the exploitation of the angular selectivity of planar Bragg gratings. A proof-of-concept will be demonstrated for operation at Ka receive band (17.3-21.2 GHz). • To develop numerical tools for electromagnetic computation and fast design. Technologically, this work will rely on the following development: • Synthesis of high permittivity filaments for additive manufacturing • Software and hardware developments required for the direct printing of a permittivity spatial gradient, first in planar form and then in non-developable 3D form. The dual applications of the proposed functionalized layer in ALADDIN are obvious. First, the improvement of satellite communication robustness is a major stake of future combat systems because of their highly cooperative nature. In addition, beyond satellite-airplane communications, the technologies and methods developed in ALADDIN are applicable to communications between platforms in general, air-, land- or sea-based. It is also worth noting that the main driver for these satellite communications is commercial air travel. Indeed, the multiplication of constellations has enabled the emergence of the massive IFEC market (« In-Flight Entertainment and Connectivity ») which offers on-board high data-rate connectivity solutions to travelers all around the world. In this architecture, the capacity of antenna systems to maintain a good throughput when the satellite is getting closer to the horizon is critical. The market stakes related to the development of SATCOM antenna systems are also important. In this highly competitive landscape where north-American and Asian competitors are numerous, the ALADDIN project will contribute to provide a technical differentiator in support of the French defense and civil industries.
