Docket R4111 ARRAY ANTENNA SYSTEM EAO:meh ABSTRACT OF THE DISCLOSURE An array antenna for radiating wave energy signals into a selected region of space and suppressing radia- tion in other regions of space is formed with an aperture which is an array of N antenna element modules, each comprising two or more antenna element groups, and each group comprising one or more antenna elements. A plurality of 2N first transmission lines is provided, each for supplying wave energy signals to one of the element groups. The antenna also includes N second transmission lines. Each of the second trans- mission lines has an input terminal, intersects a selected number of first transmission lines, and is terminated at its other end. Directional couplers are provided for coupling the second transmission lines to the intersected first transmission lines. The directional couplers have selected coupling ampli- tudes and coupling phases to cause signals supplied to any of the input terminals to be coupled pri- marily to the elements of the element module corres- ponding to the input terminal, and to be coupled with selected relative amplitudes and phases to selected elements in other element modules of the array. - 1 -
