摘要
叙述了FAST(500m口径球面射电望远镜)30m模型L-波段馈源的设计、制作和性能测试过程。馈源的设计仿真使用了HFSS软件,并选用纸板或塑料板和铝箔胶带,通过手工操作完成馈源制作。馈源的性能通过测试表明满足FAST30m模型天文观测的需要。文中采用的HFSS软件仿真及手工制作馈源的方式不失为形式简单的馈源的模型制作的一种快速、经济和有效的方法。这种方法对相近的工作有一定的参考价值。
In this paper, the design, manufacture and test of the L- band feed for the FAST 30m demonstrator are presented. The HFSS is used for the simulation during the design. The feed was made by hand using cardboard, plastic borad and adhesive aluminum foil tap. The test measurement shows that this manually made feed meets the required specificaion of the FAST 30m demonstrator. The design using the HFSS and manufacture by hand might be a fast, economical and effective method for producing simple feed and may be helpful to other similar work.
