Abstract
A multi-beam feeding apparatus according to the present invention is a feeding apparatus for a multi-beam antenna comprising a reflector and a primary radiator comprising a plurality of element antennas, and the apparatus is provided with a plurality of beam forming networks for setting an excitation distribution relative to the element antenna necessary for every beam. Each beam forming network is connected via a combiner (a divider) disposed to every of all the element antennas. According to this construction, not only there is such an advantage that a variation of capacity of communication between the beams and the like can be flexibly responded, but also there are such effects that a beam forming network can be so simply constructed that the same systems are only combined, a power can be more effectively used, such a problem as a heat generation and the like can be reduced. Moreover, a plurality of missions can be easily fused. Thereby, communication can be more flexible, a power loss relating to a large power transmission can be easily solved, and an necessary excitation distribution can be easily set at a low cost.
