Abstract
A device for delaying signals fed to radiating elements of an array antenna by providing delay paths of selective lengths between respective antenna elements and a signal input source. A plurality of first optical fibers are provided, each having a selected length. A plurality of second optical fibers are also provided, each having a selected length. The first output fibers are alignable to the second fibers to form respective delay paths. At least one of the set of first fibers and set of second fibers is movable relative to the other so that when moved, selected first fibers are aligned with selected second fibers creating a particular delay path of a selected length from the input source to each radiating element.
