Design a transmission line segment that matches 300 Ω to 50 Ω at 10 GHz using a quarter-wave match. W is the width of the microstrip trace. The reason for this is that the conductor width scales with substrate height, so thicker substrates mean fatter conductors. This parameter is used for the loss calculations. Enter the values of trace width (w), trace thickness. In most practical cases, the dielectric substrate is electrically thin, that is, h ≪ λ. Visit Microstrip.
