Signal Reflectivity and Absorption
|
Radio signals are reflected or absorbed depending on the material they come in contact with. Because linear polarized antennas are able to “attack” the problem in only one plane, if the reflecting surface does not reflect the signal precisely in the same plane, that signal strength will be lost. Since circular polarized antennas send and receive in all planes, the signal strength is not lost, but is transferred to a different plane and is still utilized. As a result, circular polarized antennas provide a higher probability of a successful link because it is transmitting on all planes. |
