Abstract
Disclosed is an array antenna comprising a plurality of array elements. The plurality of array elements are formed as a coupler including a central element and peripheral elements configured to surround the central element; each of the central element and the peripheral elements is formed as a waveguide; and the peripheral elements are excited in higher-order modes using coupling slots to form a beam pattern through an electric field distribution of the central element and the peripheral elements.

An array antenna comprising:
- a first array structure including a plurality of first array elements consisting of a first central element and first peripheral elements configured to surround the first central element, each of the first central element and the first peripheral elements being a waveguide, and the first peripheral elements exciting higher-order modes through coupling slots to form a beam pattern by electric field distributions of the first central element and the first peripheral elements;
- and
- a second array structure including a plurality of second array elements consisting of a second central element and second peripheral elements configured to surround the second central element, each of the second central element and the second peripheral elements being a waveguide, and the second peripheral elements exciting higher-order modes through coupling slots to form a beam pattern by electric field distributions of the second central element and the second peripheral elements,
- wherein the first central element is one of the second peripheral elements, and the second central element is one of the first peripheral elements.
