Shaped reflectors form one of the cornerstones of satellite telecommunications today, and have in all but a few cases replaced the array-fed parabolic reflector antennas for contoured beam...
The possibility of employing the same spacecraft at several orbital locations, changing the coverage region, and compensating for varying weather conditions are the main reasons why reconfigurable...
A feasibility study of a shaped dual reflector antenna equipped with a reconfigurable subreflector for a realistic mission scenario in Ku band is presented. The reconfigurable surface will be...
This paper demonstrates that adapting the reflector surface shape of a spacecraft antenna according to the actual weather situation can reduce the transponder power margin by as much as 6 dB. The...
In a quasi-optical network the beams are usually focused and guided through the system by means of curved and planar mirrors. Physical Optics (PO) is an accurate analysis tool for these elements,...

The present paper describes the determination of the scattering from the LICEF antenna elements on the SMOS satellite taking into account that the solar panels rotate during the flight of the...
The new light-weight reflector antenna technology being used by several spacecraft companies requires accurate electromagnetic modelling of the reflector surface properties. In particular, the new...
