Antenna reflection loss
Nov 19, 2016

As pointed out above, when the feeders and antenna matching, no reflection on the feeder, just wave, that is transfer only to the direction of the antenna on the feeder. At this time, the feeder throughout the range of voltage and current are equal, feeder at any point on the impedance is equal to the characteristic impedance.

And when the antenna and feeder does not match, that is, when the antenna impedance equal to the characteristic impedance of feeder, load can absorb part of the high-frequency energy feeder transport, but not all, absorbed that energy will be reflected back form a reflected wave.
