From: A Novel Broadband Band-pass Filter Based on Spoof Surface Plasmon Polaritons
The configuration of SSPPs filter.
(a) Top view of the proposed broadband filter, in which l1 = 5 mm, l2 = 50 mm, and l3 = 115 mm. (b) CPW structure, in which g1 = 0.13 mm, g2 = 0.26 mm and H = 5 mm. (c) Matching transition with the gradient grooves and flaring ground, in which k = 4/45. (d) Zoomed view of the couple structure, in which G = 1.8 mm, L = 7 mm, h = 4 mm, p = 5 mm and a = 2 mm. (e) Zoomed view of the split ring, in which L1 = 8 mm, L2 = 2.1 mm, G1 = 0.4 mm and G2 = 0.15 mm.
