Impedance of waveguide
WitrynaI used the equations from Coplanar Waveguide Circuits, Components, and Systems from Rainee N. Simons (2001). The Edge-Coupled CPWG can be found at pages 190-193. My Calculation Let h = 1.6, S = 0.35, W = 0.15, d = 0.15, ϵr = 4.6. r = d d + 2S = 3 17 k1 = d + 2S d + 2S + 2W = 17 23 δ = { (1 − r2) (1 − k21r2)}1 / 2 ≈ 0.992787 Witryna30 mar 2024 · Characteristic impedance is the ratio of voltage to current needed to form a propagating wave along the line. The input impedance will equal the characteristic impedance only if there's no reflection returning to the input from the transmission line structure or its termination.
