In the last years scientific community has been witness of the growing interest in global EHF satellite systems for broadband communications; these systems can help national and regional telecommunications service operators to provide broadband communications in areas not adequately served by terrestrial systems. In this paper main EHF satellite missions are presented, outlining challenges and future...
It is recognized that W band will be one of the frontier of satellite communications. Pioneering work on the scientific testing of high frequency satellite communications have been DAVID (data and video interactive distribution) mission and WAVE (W band analysis and verification) project, both of them funded by the Italian Space Agency (ASI). The WAVE project was a feasibility study carried out in...
This paper presents the payload design for an in orbit test of W band technology called IKNOW mission (In orbit Key-test and validatioN Of W band). The increasing demand for frequency bands with large bandwidth availability to satisfy satellite communications applications requirements renders mandatory the need to explore higher and higher frequency ranges. W band (75-110 GHz) could represent the...
