Link budget analysis for future E-band gigabit satellite communication links (71-76 and 81-84 Ghz)

摘要

The paper shows the feasibility of a satellite-earth downlink in E-band (60-90 GHz) taking into account both the expected channel attenuation and hardware characteristics. For low earth orbit (LEO) applications, the attenuation and the link are studied as a function of the elevation angle seen at the ground station. Link budget calculations for a realistic scenario indicating the feasibility of broadband and multi-gbit/s E-band communication between LEO satellites and ground stations with available receive antenna sizes and availabilities above 98% are presented. Additionally, a possible E-band geostationary earth orbit (GEO) link budget with 5 Gbit/s of data rate is presented, including atmospheric losses.
