I'm relatively new to antennas. In most of the textbooks, it is said that we want to minimize standing waves in the transmission lines by matching the characteristic impedance of the line with the antenna's impedance.
My confusion is regarding the following two questions:
- If the antenna and the line are perfectly matched there are no standing waves in the line?
- If so, what happens to these traveling waves once they reach the end of the dipole antennas. Most pictures show that there are actually standing waves on two sides of the dipole. It is clearly seen here that there are standing waves:
Image source: "Animation showing the sinusoidal standing waves of voltage, V (red) and current, I (blue) on a half-wave dipole driven by an AC voltage at its resonant frequency" from Dipole characteristics on Wikipedia, Dipole antenna
Does it mean that standing waves occur in line as well?
PS. An excerpt from C. Balanis book on antennas third edition page 18, which clearly says that there are standing waves in the dipole antenna.
