Abstract:
1. A phased array comprising at least three adjacent plates each comprising at least one support structure for a radiating element of the antenna and two opposing sides facing respective adjacent plates of the antenna, wherein the opposing sides of each of the plates are different from one another, and a screw assembly for maintaining a substantially constant gap between the support structures of the at least three adjacent plates, the screw assembly comprising: a first screw comprising: a second screw configured to engage the second threaded surface of the first screw to maintain a substantially constant gap between the respective support structures of the first and second plates; a third screw comprising an exterior surface comprising a third threaded surface arranged with one of a right-hand thread or a left-hand thread, and an inner wall defining a bore coaxial with a longitudinal axis of the third screw and comprising a fourth threaded surface with the other one of a right-hand thread or a left hand thread; a fourth screw configured to engage the fourth threaded surface of the third screw to maintain the same substantially constant gap between the respective support structures of the second and third plates; wherein the second plate has a first bore configured to receive the second screw and a second bore having a different profile than the first bore configured to receive the third screw; and wherein a gap between the respective sides of the first and second plates is different from a gap between the respective sides of the second and third plates.
