Next generation LEO (Low Earth Orbit) System (NeLS) that would provide a global multimedia mobile satellite service for handheld user terminals has been studied by the Next-generation LEO System Research Center. The system needs large active phased array antennas on board the satellites. Therefore, it is essential to develop a two-dimensional deployable antenna panel. In this paper, a deployment sequence for active phased array antenna is proposed. The sequence will be able to provide a stiff and accurate antenna. Also, new types of hinge and latch mechanism are proposed for the antenna. Each hinge is located at reverse side of the panels after deployment, there is neither gap between panels. The newly developed latch pulls the shaft into the holder with very low torque, after the shaft is latched incomplete. The effectiveness of the proposed hinge and latch mechanism were confirmed by experiments. Next, we will develop the two-dimensional deployable panel for active phased array antenna by the proposed sequence with the proposed hinge and latch.
