Abstract
The Five-hundred-meter Aperture Spherical radio Telescope (FAST), which is currently under construction, is proposed to be equipped with phased array feed (PAF) to improve survey speed and compensate for the feed cabin vibration, and a study is underway for this. In this paper, the L-band FAST PAF plan is introduced,and the design of antenna array element is presented in detail. The measured results of the fabricated element validate the element design.
