| Abstract: | Aiming at the requirements of near space vehicle TT＆C,a Ka-band multiple-beam reflector antenna is proposed in this paper. The realization form of antenna is analyzed and the relation between coverage area and the position of offset feed is discussed. The influence of focus to diameter ratio and that of subreflector dimension on performances the offset beams are described. The obtained re- suits will be helpful for optimal design and operation of antenna. |
| Keywords: | near space Ka-band TT&C multiple-beam reflector antenna offset beam |
