System level comparison of broadband satellite communications in Ka/Q/W bands

This work compares different solutions using Extremely High Frequencies (EHF) for broadband satellite communications. Advantages and drawbacks of each solution are discussed accounting for the most important features needed to achieve very high capacity systems (i.e. multibeam capabilities, bandwidth, signal attenuations and impairments) and the most important features needed for commercial success (i.e. use cases, cost per bit, cost of the terminal).
