The mathematical equation is – D0 = 15 * N * C2S / λ03 The following mathematical term gives the Axial Ratio or the AR. AR = 2N+1 / 2N The following expressions give the generalized far-field pattern. E = sin (π/ 2N) cosϴ sin [ (N/2) * Ψ] / sin (Ψ /2)
WebRadiation is the term used to represent the emission or reception of wave front at the antenna, specifying its strength. In any illustration, the sketch drawn to represent the radiation of an antenna is its radiation pattern. One can simply understand the function and directivity of an antenna by having a look at its radiation pattern.
