An antenna which behaves identically in all directions.
Pertaining to a material with properties, such as density, electrical conductivity, electric permittivity, magnetic permeability, or refractive index that do not vary with distance or direction. In a perfect void, no loss of power is apparent regardless of distance or direction. Does a perfect void exist
an antenna that radiates equally in all directions
a theoretical antenna that radiates power with unity gain uniformly in all directions
a theoretical antenna with equal gain to all points on isotropic sphere
a theoretical beast that radiates equally in all directions
a theoretical (can't actually build one, buy one, or find one in nature) ideal omnidirectional antenna
A hypothetical, lossless antenna having equal radiation intensity in all directions; used as a zero-dB gain reference in pattern measurements or directivity calculations.
An emitter of constant radiance with angle. Isotropic radiators obey Lambert's law.
An isotropic radiator is a theoretical point source of waves which exhibits the same magnitude or properties when measured in all directions. It has no preferred direction of radiation. It radiates uniformly in all directions over a sphere centred on the source.
