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.
Claims5
An array antenna comprising:
- a plurality of radiation elements that excite a first polarized wave and a second polarized wave different from the first polarized wave,
- wherein a first power feed point that excites the first polarized wave and a second power feed point that excites the second polarized wave are disposed on each of the radiation elements,
- the plurality of radiation elements are arranged in an array or in a matrix, and
- the plurality of 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 a center of each of the radiation elements with respect to a reference line extending from the center to the first power feed point.
