3-14CHARACTERISTIC IMPEDANCE OF A TRANSMISSION LINE
You learned earlier that the maximum (and most efficient) transfer of electrical energy takes placewhen the source impedance is matched to the load impedance. This fact is very important in the study oftransmission lines and antennas. If the characteristic impedance of the transmission line and the loadimpedance are equal, energy from the transmitter will travel down the transmission line to the antennawith no power loss caused by reflection.
