英文摘要A cross bow-tie dipole feed with cavity and symmetrical E and H plane pattern is presented for the Five hundred-meter Aperture Spherical radio Telescope (FAST). In this paper we describe the design, optimization and simulation results of a wide-band cross dipole feed with cavity covering the frequency range from 300 MHz to 600 MHz for FAST. The main goals of our design are to ensure that, (1) we cover the octave bandwidth, (2) the feed has symmetrical E and H plane pattern, and (3) the physical dimension is suitable for mounting it in the reserved position of the FAST feed cabin. The initial results indicate that we have met most of our design goals. This kind of feed had been equipped with the multi-beam receiver to carry out observation on the platform of FAST cabin.
