Abstract
An array antenna includes two different types of super elements each having transmit/receive (TR) modules coupled thereto. The TR modules are widely spaced and the super elements are arranged such that by selectively activating certain ones of the super elements the antenna provides a dual field of view in elevation. A Narrow Field of View (NFOV) is achieved by activating all super elements in the antenna aperture. A Wide Field of View (WFOV) utilizes only super elements which are arranged in a center portion of the antenna aperture.
