WebIn electromagnetics, directivity is a parameter of an antenna or optical system which measures the degree to which the radiation emitted is concentrated in a single direction. It is the ratio of the radiation intensity in a given direction from the antenna to the radiation intensity averaged over all directions. Therefore, the directivity of a hypothetical isotropic … WebSep 12, 2024 · 10.8: Radiation Pattern. The radiation pattern of a transmitting antenna describes the magnitude and polarization of the field radiated by the antenna as a function of angle relative to the antenna. A pattern may also be defined for a receiving antenna, however, we defer discussion of the receive case to a later section. WebHowever, in antennas world, it is acceptable that we can consider an antenna as circullar polarized even if its sxial ratio reaches 3 dB as a maximum.
