Summary
DescriptionAntenna directive gain diagram.svg |
English: Diagram explaining how the directivity (directive gain) of an antenna is defined. R (grey) is the radiation pattern of a typical directive antenna. It radiates most of its power in a narrow lobe oriented along the z axis. Riso shows the radiation pattern of a hypothetical isotropic antenna| that radiates the same total power as the first antenna but radiates it equally in all directions. Isotropic gain G is defined as the ratio of the power density S (in joules per square meter) radiated by the antenna in the direction of its main lobe (here the z-axis) to the power density Giso radiated by the isotropic antenna
