a diagram that allows us to visualize in what directions the energy will radiate from an antenna
The way in which a speaker disperses sound.
A drawing of the coverage of speaker using a polar graph.
The polar response characteristics of a loudspeaker system at all frequencies. Along with power response, the R-P is what mainly determines the subjective impression of a loudspeaker. In a microphone, this might be called its radiation-pickup pattern. See also Polar response; Dispersion
Each sound-emitting object can optionally radiate sound in a certain pattern (rather than uniformly all around it). For example, a head should emit sounds in the direction that its nose is pointing.
A diagram showing the intensity of the radiation field in all directions from a transmitting radio or radar antenna at a given distance from the antenna.
A three-dimensional representation of the gain of a transmit or receive antenna as a function of the direction or radiation or reception.
The graphical representation of the relative field strength radiated from an antenna in a given plane, plotted against the angular distance from a given reference.
A graphical representation in either polar or rectangular coordinates of the spatial energy distributions of an antenna.
In the field of antenna design the term radiation pattern most commonly refers to the directional (angular) dependence of radiation from the antenna or other source (synonyms: antenna pattern, far-field pattern).Constantine A.
