Abstract

Fifth-generation mobile communication system (5G) array-antenna transmitters attached to space deployable membrane structures were developed by the authors. The array-antenna mission’s main objectives are measuring the transmitters’ communication power and demonstrating the antenna’s non-flatness compensation function by beam-forming technology in Low Earth Orbit. Thermal design of the transmitters is critical for the mission’s success. Thus, this study demonstrates the process of designing Multi-Layer Insulation (MLI) to protect the 5G array-antenna transmitters from the harsh space environment. The design process includes thermal analysis, in-house fabrication of the MLI, and the thermal equilibrium test for correlation. The analysis reveals that the temperature of the radio-frequency integrated circuit in the transmitters can remain within the allowable temperature range by appropriately selecting the beaming period and satellite attitudes.
