Transmission lines are needed for connecting various circuit elements and systems together. Open-wire and coaxial lines are commonly used for circuits operating at low frequencies. On the other hand, coaxial line, stripline, microstrip line, and waveguides are employed at radio and microwave frequencies. Generally, the lowfrequency signal characteristics are not affected as it propagates through the line. However, radio frequency and microwave signals are affected signi®cantly because of the circuit size being comparable to the wavelength...
