Summary:
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.
