| Abstract(in English) | Simple single-reflector beam scanning antennas are realized by only paraboloidal main reflector moving. The antennas have advantages of simple configuration and high reliability due to absence of rotatable or flexible RF components. Therefore these can be possible candidates for low-cost earth station antennas in broadband mobile satellite communications. In this report, we present the optimum configuration and the design method for the antenna. The optimum means that the worst second-order aberration is minimized within the entire beam scan range, because the second-order aberration is the main cause for performance degradation under the beam scanning. The design method is validated by the physical optics analysis for the design examples. In this report, we ignore the feed blocking influence. |
