SPACE PHASED ARRAY ANTENNA DEVELOPMENTS: A PERSPECTIVE ON STRUCTURAL DESIGN
As the "right-hand man" to space communications, navigation, environmental monitoring, and other satellite
systems, the space active phased array antenna is capable of scanning and covering long distances and large
scale ranges through its complex deployment mechanism, large physical aperture, and lightweight structural
design. In comparison with mechanical scanning antennas, the space active phased array antennas can realize
flexible beam scanning through the active phased array principle, while simultaneously achieving a high
gain, low sidelobe, high resolution, and high reliability. Improving the comprehensive performance of the
satellite is crucial with the rapid development requirement and large application field. In this article,
the development history of the space active phased array antennas is summarized, and these antennas are
characterized by the following structural features: large aperture, deployment mechanism, and lightweight
configuration. The state of the art of space deployable active phased array antennas is also presented. Furthermore,
seven crucial design technologies of antenna essential components are discussed, and the development trends of
structural technologies of the space deployable active phased array antenna are demonstrated.
