作为下一代最大的射电望远镜，平方公里阵列（SKA）现在已经进入了前期建设阶段。中国从上世纪90年代初就加入了这一长征，并作出了重要贡献。本文简要回顾了SKA的概念，并详细描述了SKA天线所面临的挑战。然后介绍了中国制造的两个SKA天线的概念设计，即中国天线验证天线（DVAC）。设计包括微波光学、天线结构和伺服系统，以满足预期的SKA要求。最后对两种设计方案进行了比较，并选择其中一种作为SKA天线的候选方案。
The SKA (Square Kilometre Array), being the next-generation largest radio telescope, has now stepped into the pre-construction phase. China has joined this long march since the early 1990s and made significant contributions during this process. In this paper, a brief review of the SKA concept and detailed description of the challenges for the SKA dishes are given. Then two concept designs for the SKA dishes made by Chinese, the Dish Verification Antenna China (DVAC), are presented. The designs including microwave optics, antenna structure and servo system are carefully carried out to meet the intended SKA requirements. Comparison of these two designs is made in the end and one of them is selected as a candidate for the SKA dishes.
