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.
