This paper gives an overview over the essential physical phenomena of the satellite communications channel, with particular emphasis on the land mobile satellite (LMS) channel. Then it describes measurement and modelling techniques for the LMS channel and gives an overview over this field. The characteristics of the LMS channel are discussed, and “historic” DLR channel measurements are reviewed. From...
This paper provides information about a mobile low-profile satellite tracking antenna with dual-band performance and a reconfigurable circularly polarised radiation pattern, realised by Ka-band sub-aperture panels located on a mechanical azimuth positioner. The design and measurement results of a leaky-wave antenna panel, selected for this purpose, as well as a tracking antenna prototype are presented...
