| Abstract: | With developing trend of miniaturization, integration and multi-function for satellite payloads, antenna that have features of ultra-wideband, high gain and beam flexible is a very hot research topic in space-borne antenna community, because it can be used for different applications such as communication, interference, reconnaissance, detection systems and has a very urgent demand. Firstly, antenna elements with different technologies are summarized in this paper. Based on the characteristics of electrical, mechanical and adaptability to the space environment of different antenna elements, preferred antenna elements are recommended. Then, different beam forming technologies are introduced. Advantages and disadvantages and their applicability on satellite platforms are analyzed. In addition, key technologies and main approaches of ultra-wideband phased array antenna are depicted. Lastly, developing trend for space application are proposed, which will be a guideline for study and engineering application of ultra-wideband phased array antenna. |
