The in-flight pattern measurements of a sub-millimetre space telescope may be improved by determining the actual reflector anomalies and then include the knowledge to these in the final pattern de-termination. The pattern measurements with a celestial object as source often…

A stand-alone commercial program, performing advanced electromagnetic processing of measured data, is being developed by TICRA. The program reads the measured field and computes the extreme near field or the currents on the antenna surface. From the inspection of the…

Very sophisticated antenna models are available today for the accurate prediction of antenna performances, in particular those included in the European Antenna Modeling Library in which GRASP, ADF and SATSim are key components. However these models are not directly suitable…

This paper presents an improved inverse Method of Moment technique that allows surface currents to be reconstructed on the surface of an antenna. The input to the algorithm is measured near- or far-fields and the method therefore allows antenna engineers…

This paper describes various aspects of a reconfigurable reflector antenna for future space applications. The reflector surface consists of an RF net made by thin interwoven piano wires. This net provides the necessary reflectivity at Ku-band frequencies. The RF net…
