2 Electrical Transmission Lines

In this chapter the transmission of waves at high frequency through transmission lines is studied. Transmission and reflection coefficients along transmission lines are important in the excitation of wire lines in transmission and receiving circuitry of radio frequency (RF) waves.

2.1 Model of Time-Harmonic Waves on Transmission Lines

A transmission line is critical for waves to propagate from the source to the radiation devices, or from the receiving devices to the receiver. When the wavelength of the waves, the carrier, is compatible with the size of the transmission line, then lumped circuit treatment can no longer be valid. Both transmission and reflection of the waves can occur. This section gives an introduction ...
