Radiation Pattern
The variation of the field Intensity of an antenna as an angular function with respect to the axis.
Note: A Radiation pattern is usually represented graphically for the far-field conditions in either horizontal or vertical plane.
2. In Fiber optics, the relative power distribution at the output of a fiber or Active Device as a function of position or angle.
Note 1: The near-field radiation pattern describes the radiant emittance (W•m-2) as a function of position in the plane of the exit face of an optical fiber.
Note 2: The far-field radiation pattern describes the irradiance as a function of angle in the far-field region of the exit face of an optical fiber.
Note 3: The radiation pattern may be a function of the length of the fiber, the manner in which it is excited, and the wavelength. Synonym Directivity pattern.
