Moreover, the chapter covers the most commonly used printed-circuit transmission lines for RF systems, which also include those that can be realized in multilayer structures that are attractive for printed-circuit antennas and associated RF circuits. It also presents synthetic transmission lines, a class of transmission lines that can be implemented using only lumped elements, which could be useful for RF circuits needed for on-chip antenna interface. It includes the transmission-line equations and important transmission-line parameters such as characteristic impedance, propagation constant, phase velocity, effective relative dielectric constant, dispersion, loss, distortion, impedance, reflection coefficient, etc. This chapter presents the theory of transmission lines, which are essential for the design of radiofrequency (RF) circuits associated with antennas and transmission-line-based antennas.
