PROBLEM TO BE SOLVED: To provide an array antenna capable of simplifying a configuration of a feeder circuit while including a plurality of paths.SOLUTION: An array antenna 1 comprises groups A, B, C, and D each including a plurality of radiation elements 10 which are arranged in such a matrix shape that even numbers of radiation elements are included in a horizontal direction and a vertical direction. Signals of a system that is different from each other are supplied to each of the groups A, B, C, and D. The plurality of radiation elements 10 in each of the groups A, B, C, and D are set in such a manner that power supply phases for power supply of signals are equal or the power supply phases are made reverse in one of or both the horizontal direction and the vertical direction for a pair of neighboring radiation elements 10 without being overlapped among the groups A, B, C, and D.SELECTED DRAWING: Figure 2 |
