ABSTRACT:
A space-fed array is selectively operable in a reflective mode or in a feed-through mode. The array includes, in an exemplary embodiment, a primary array; and a feed array. The primary array includes a first side set of radiating elements, a first set of phase shifters, a set of switches, a second set of phase shifters and a second side set of radiating elements. Each of the switches is connected between corresponding ones of the first set and the second set of phase shifters and ground, selectively settable at an open position or at a closed position. The open position corresponds to the feed through mode, and the closed position corresponds to the reflective mode.
