PROBLEM TO BE SOLVED: To provide a power distribution method which is improved to enhance front-to-back ratio (F/B) and front-to-side ratio (F/S) characteristics of an array antenna, to provide a distributor to which the distribution method is applied, and to provide an array antenna to which the distributor is applied. SOLUTION: In a method in which a power is divided and supplied to each radiating element of an array antenna, a power applied to a power feeding unit is divided into two at a first stage of distribution, either one of two divided powers is supplied to a center side radiating element and another is further divided and supplied to each outside radiating element. Thereby, a large amount of power is supplied to the center side radiating element and a relatively small amount of power is supplied to the outside radiating element. In the power distribution method, the power is supplied to the center side radiating element in series when a quantity of the center side radiating element is one, and supplied in parallel when a quantity of the center side radiating element is two or more. A power is supplied to the outside radiating element in parallel. The power distribution method is implemented on a dielectric substrate. COPYRIGHT: (C)2008,JPO&INPIT
