Consider a parallel plate transmission line that has a width of 3 cm. It is filled with Teflon. Part of the transmission line has a height of 2 mm. The rest of the transmission line has a height of 8 mm. Design a transmission line matching section that will pass 100% of a 200 MHz signal from the narrow height transmission line to the high transmission line. What possible issues arise with your design that are not covered by the transmission line approach
