In electrodynamics, circular polarization of an electromagnetic wave is a polarization state in which, at each point, the electromagnetic field of the wave has a constant magnitude and is rotating at a constant rate in a plane perpendicular to the direction of the wave.
Polarization diversity combines pairs of antennas with orthogonal polarizations (i.e. horizontal/vertical, ± slant 45°, Left-hand/Right-hand circular polarization etc.). Reflected signals can undergo polarization changes depending on the medium through which they are traveling.
The polarization (or polarisation) of electromagnetic (EM) waves or fields is introduced. This leads into the discussion of antenna polarization. Linear polarization (horizontal or vertical pole) is discussed. RHCP and LHCP (left and right hand circular polarizations) are described.
Antenna Polarization is defined as the orientation of the electric field vector of the radiated electromagnetic wave by the antenna with a negligible amount of losses.
28 Ιουλ 2022 · Polarization works in two ways: the more closely two antennas are aligned and have the same polarization, the better the received signal strength will be. Conversely, poorly aligned polarization can make it more difficult for an intended or undesired receiver to capture enough useful signal.
29 Αυγ 2018 · The direction of oscillation of the electric field component, when a radio wave is propagating in a medium, is called the polarization of the radio wave. Antennas are usually developed to receive and transmit radio waves that are polarized in a specific way.
