Branch-line couplers are widely used for satellite antennas. In this paper we describe different types of branchline couplers and their use for satellite antennas.
This paper will focus on the investigation and development of microwave components for applications in multimedia satellite communication. This effort is part of the national R&D project MULTIFEED, which is funded by German DLR/BMWI. The goal of the project is the realization of a Multiple Feed per Beam antenna, that is capable of reducing the satellite payload while maintaining full area coverage...
Since 2008 the lightweight intersatellitelink antenna (LISAMS) has been developed for establishing communication between low flying satellites (e.g. earth observation satellites) and geostationary relay satellites. For this development a detailed electrical design has been simulated to predict performance parameters. The paper describes the detailed component design and the comparison of the simulated...
This paper describes the design of a multiple spot beam satellite antenna with overlapping beams in Ka-band. It has been designed in the frame of the DLR granted R&D program ldquoMedusardquo. We discuss the principle of a multiple feeds per beam (MFB) antenna in comparison to a classical single feed per beam (SFB) antenna. Results for the optimisation of antenna and feed network are given.
