This paper investigates the application of symmetrical two-layer FSSs to a planar array antenna to reduce its backward RCS. The symmetrical two-layer FSSs is based on the band-pass FSS design. A planar array antenna covered with FSSs is designed and constructed. The simulated results show that at working frequency the backward RCS of antenna array with FSS has dramatically reduced than that of the common antenna array.
