Compared with conventional satellites, small satellites can drastically reduce launch costs and increase the number of satellites in LEO. However, small satellites face the more severe issues in terms of power consumption and radiation tolerance due to the limited size of solar panels and more than ten times thinner radiation shield than conventional sizeable satellites. In addition, since the small satellites cannot have the large-size antenna installed on the main body, a deployable membrane is
