Abstract
An array antenna includes radiation elements that excite a first polarized wave and a second polarized wave, and that are arranged in an array. A first power feed point and a second power feed point are disposed on each of the radiation elements. The radiation elements include a first radiation element in which the second power feed point is located at a position of +θ° (0<θ≤90) in a direction circling around a center of each of the radiation elements with respect to a reference line extending from the center to the first power feed point, and a second radiation element in which the second power feed point is located at a position of −θ° in a direction circling around the center with respect to a reference line extending from the center to the first power feed point.
