A Wideband Dipole Feed for Big Reflector Antenna

摘要：

　　A wideband dipole feed with symmetrical E&H plane patterns is presented for use in reflector antennas.In this paper we describe the design, construction and characterization of a wideband dipole feed for FAST antennas covering the frequency range 70 to 140 MHz.Main goals of our design are, 1)covering octave bandwidth, 2) the feed has symmetrical E & H plane patterns, and 3) the physical dimension is suitable for mounting it in the reserved position of the FAST feed cabin.We hope that four frequency range of FAST antennas will be equipped with this wideband dipole feeds.Preliminary simulation results indicate that we have met most of our design goals.
