Unformatted text preview: sense. It is simply a ratio of magnitudes of the traveling waves. Lossless Transmission Line Model: We will now represent a TL Section with this model: Calculating Z o • Using table 21, (TL parameters R,L,G,C for various geometries) we can calculate Z for different TL geometries. • For simplicity, let’s assume the TL’s are lossless. Ex. Parallel Plate TL L C ( ) (0 ) ( ) (0 ) R j L j L L Z G j C j C C ϖ + + = = = + + L d Z C w μ ε = = Free Space Z o • The wave impedance is defined as sqrt(u/e) • For Free space u = uo and e=eo therefore Zo = 377 Ω for free space. Microstrip Transmission Line...
