Brief description of the technology solution and the added value it provides <\/strong><\/h4>\n

The current onboard multi-spot satellite antennas and their corresponding ground feeds require dual-frequency band and circular polarization. There are currently two technological solutions that have several power restrictions and\/or a very high cost due to their mechanical complexity. The new feed architecture of the invention is based on a Diplexer + Biphase-Polarizer. It provides excellent electrical specifications (Isolation and Axial Ratio) with a very simple low-cost mechanical structure .<\/span><\/span><\/p>\n

Description of the technological base<\/strong><\/h4>\n

AFeNSat (Antenna Feeding Network for New Generation Satellite Communications) is based on the combination of a Diplexer and a new Biphase-Polarizer. This new configuration provides enhanced electrical characteristics: bandwidth, matching, Axial Ratio (AR) and isolation that solve the restrictions of the actual feeds based on the combination of OrthoMode Transducer (OMT) and corrugated Monophase Polarizer. Also, this solution simplifies the mechanical fabrication with the subsequent cost saving compared with the six-port junction-based alternative.<\/span><\/p>\n

The new feed, unlike current, no need of alignment of its components, thereby providing great versatility to the antenna structure, which can be used to reduce their size and complexity.<\/span><\/p>\n
