![]() Let us look at the pattern of energy radiation. Radiation Patterns are diagrammatical representations of the distribution of radiated energy into space, as a function of direction. The energy radiated by an antenna is represented by the Radiation pattern of the antenna. This is a mathematical function of radiation properties of the antenna represented as a function of spherical co-ordinates, E (θ, Ø) and H (θ, Ø). ![]() Graphically, radiation can be plotted as a function of angular position and radial distance from the antenna. The power when radiated from the antenna has its effect in the near and far field regions. One can simply understand the function and directivity of an antenna by having a look at its radiation pattern. In any illustration, the sketch drawn to represent the radiation of an antenna is its radiation pattern. ![]() Radiation is the term used to represent the emission or reception of wave front at the antenna, specifying its strength. ![]()
