Design of Low Loss Beam Forming Networks -Supported by Numerical Simulations and Material Characterisation
Beam forming networks (BFN) distribute transmission signals to an antenna system at satellites in the orbit which enable energy-efficient multi-media communication. A new approach to BFN is presented which combines structural and electrical functions in a single multilayer board in contrast to traditionally milled metal bodies. In detail, a BFN feeds an array of radiators which illumi nates an antenna reflector. A multilayer board offers a 3d inte gration with very short interconnects. Dielectric layers made of syntactic foam (SF) enable low insertion loss and high phase stability which are required for high performance in microwave applications. SF is a light weight composite with good compressive strength and space heritage. It is made up of hollow spherical glass fillers, which are embedded into a plastic matrix, and offers a dielectric constant around l.4. Arranging the BFN perpendicular to the antenna. is state of the art.
