“…Traditional antenna farms made of 4 multiple beams reflector antennas, and based on Single Feed per Beam [1] suffer from accommodation issues of the reflector on the platform. Alternative antenna architectures, such as active imaging arrays become attractive, since they can produce the requested set of multiple beams out of the same radiating aperture, and also because antenna processing may be implemented in order to maintain the shape of the beams regardless of the distortion of the main reflector, and of the satellite instability.…”

“…However, Manuscript the feed lattice must be tight enough to fulfill the beam density requirement over the coverage. In single feed per beam (SFB) focal arrays, each beam is produced by a single feed in the reflector focal plan [2]- [5]. Feeds generally operate both in transmission and reception [6].…”

In this paper, an original focal array for multibeam antenna is presented. It is based on multiple feed per beam (MFB) geometry. Each beam is produced by a cluster of feed horns illuminating a parabolic reflector. Three adjacent clusters of the focal array overlap for enhancing the illumination performance within the size-constrained array lattice. The beam-forming network is the key component and drives the overall performances of the radiating structure. It is composed of tri-dimensional interleaved couplers made of circular waveguides and interconnected by thin radial rectangular waveguides. The design, manufacturing, and measurement of a -band MFB focal array are reported. It is composed of 31 feed horns displayed in seven clusters, for a global size of about , where denotes the free-space wavelength at the lowest operating frequency. The realized gain is higher by 1 dB than the gain provided by the single feed per beam focal array having analogous size.Index Terms-Beam-forming network (BFN), directional coupler, focal array, -band, multiple feed per beam (MFB), single feed per beam (SFB).
