Any medium that confines and transmits electromagnetic energy from one point to another can be defined as a transmission line. Transmission lines are the fundamental elements of the microwave circuits and can also be used together with other passive devices. The evolution of the transmission lines and their associated technologies has been going on for more than I 00 years. The semi-insulating III-V compound semiconductor substrates are the most popular substrates for the current microwave applications, due to the high power and high cutoff frequency of Ill-V active devices made on them, as well as the low substrate loss for the passive components. A brief history oftransmission lines is introduced at the beginning ofthis chapter. The literature of the advanced transmission line techniques for Si-based microwave applications is reviewed in the latter part of this chapter. The organization of the thesis is summarized at the last part of this chapter.
