(a) Proposed square patch unit cell of the AMC surface. (a) Geometrical configuration (Ls = Ws = 24.5 mm, Wd = 22.3 mm, Ld = 13 mm, d = 2 mm, g = 0.25 mm). (b) Unit cell equivalent circuit model (Cg = 2.942 pF, Cd = 2.452 pF, Cslot = 4.85 pF, Lp = 5.842 nH, Lground = 1.42 nH). (c) Simulated reflection phase responses versus frequency.
