摘要

PROBLEM TO BE SOLVED: To flexibly adapt to various structures and to distribute transmission power to individual beam with excellent precision within the range of a desired power concentration degree, concerning a power feeder, a multi-beam antenna, a device for supporting power feeder design, a method for power feeder design, a program and a recording medium. SOLUTION: The power feeder includes a beam forming means for outputting a transmission wave, where the ratio of power to be distributed at every beam under multi-beam forming is increased/decreased in parallel with outputs whose number is equal to the number Na of elements arranged in an array antenna; and a (Nc×N) distribution integrating means comprising input terminals whose number is not larger than (Na/Nc/N), which is determined with respect to the number Na, the maximum value Nc of the number of the elements to be subjected to generate a single beam among the elements, and the rate (=1/N) of the maximum power of partial transmission wave to be radiated via the single beam in the summation of transmission wave power, and distributing and integrating the transmission wave supplied to the input terminals with respect to the elements arranged in the array antenna.
