Design、Manufacture and Test of the L-band Feed for the FAST 30m Demonstrator

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.
