Figure 5: Return loss versus frequency (a) for different values of the parameter W2 (other parameters: G = 1 mm, L2 = 11 mm, Lg = 9 mm, L2 = 5 mm, W1 = 20 mm, d1 = 0, and d2 = 0) and (b) for different values of the parameter G (other parameters: W2 = 5 mm, L2 = 11 mm, Lg = 9 mm, L2 = 5 mm, W1 = 20 mm, d1 = 0, and d2 = 0).
