Figure 6: Frequency behavior of the real part of the antenna input impedance: (a) antenna without the band notch for different values of the parameter W2, solid line: W2 = 13 mm and dash line: W2 = 16 mm (other parameters: G = 1 mm, L2 = 11 mm, Lg = 9 mm, L2 = 5 mm, W1 = 20 mm, d1 = 0, and d2 = 0,) and (b) antenna with the band notch (other parameters: Lv1 = 13.5 mm, Lv2 = 0 mm, Ln = 4 mm, S = 0.2 mm, and Ws = 1 mm).
