The membrane antenna technology is a very promising approach to obtain large aperture with light weight and low stowed volume. In the past decades, extensive studies have been carried out on active and passive membrane antennas. However, the practical spaceborne applications are rare due to many challenges, e.g., the surface accuracy maintenance, the on-orbit reliability, and the environmental compatibility. This paper summarizes the history and state-of-art progresses on spaceborne membrane antennas. Curved surface reflectors, conformal active membrane antennas, planar array membrane antennas, and planar reflectarray membrane antennas have been introduced, respectively. Radiofrequency design, deploying mechanism, material, experiment, application, and analysis method have been presented. By concluding the advantages and challenges of the current membrane antennas, this paper is aimed at providing a perspective of the existing problems and future trend of spaceborne membrane antennas.

“…Due to its ability to alter and tuning its conductivity complex, graphene can be applied in nanoantennas and other different applications. Since graphene antennas have low gain and radiation inefficiencies, the researchers assume that the graphene sheet is not exposed to any external magnetic field and has an isotropic conductivity [22,23,24,25,26].…”

As technological innovations improve over time, antennas have become an inherent piece of our everyday lives and it is essential for individuals to understand how data is moved through these devices. There are different methods of deciding how energy can be transmitted by antennas in an efficient manner, and not all things are seen on the antennas themselves, as there are a few issues that may emerge from the transmission cables that they are associated with too. A common method of deciding how an antenna can transmit signals of energy is through the analysis of its radiation pattern. The radiation pattern of an antenna is able to determine how energy is radiated or data is propagated by a particular antenna. This analysis will focus on understanding the graphs of radiation patterns, beam scanning, patterns of arrays, and other types of graphs. Understanding all of these concepts are important in order to have the ability to effectively utilize antennas such as being able to maximize the amount of distance possible when correctly positioned and also having the ability to boost signals from other devices.

“…To maintain the in-orbit imaging quality of the membrane antenna, the surface accuracy and pointing accuracy must be conserved stringently [5,6]; therefore, it is of great necessity to build a precise rigid-flexible coupling dynamic model and design an effective controller for the membrane-antennasatellite system. For orbiting space structures, like the space membrane antenna, thermal deformation and thermal stress could be considerable because of the environmental and onboard heat sources [7][8][9]. For a membrane structure whose dynamic properties are dominated by the stress distribution [10,11], thermal stress may change dynamics of the structure significantly.…”

In this paper, the thermal analysis of a membrane antenna structure is performed, and then, the rigid-flexible coupling dynamic modeling and control of the membrane-antenna-satellite system are studied with the thermal stress considered. The thermal analysis model of the membrane antenna structure is derived based on the finite element method by discretizing the structure into 1D and 2D thermal elements. Considering the thermal stress, the vibration modes of the membrane antenna structure are obtained, and the rigid-flexible coupling dynamic model of the membrane-antenna-satellite system is derived based on the hybrid coordinate method. To reduce the vibration of the membrane antenna structure caused by the attitude maneuver, the control command is designed based on the component synthesis vibration suppression (CSVS) method. Simulation results show that the dynamic properties of the membrane antenna structure are affected significantly by the space thermal environment, the vibration of the membrane antenna structure can be suppressed effectively by the presented CSVS controller, and the accuracy of the attitude maneuver will be improved significantly by the proposed control strategy.
