WebRadiation pattern A point source of radiation (known as an isotropic source) would radiate uniformly in all directions as shown below. It follows the inverse square law, i.e. when doubling the distance from the source, the energy per unit area is reduced to 1/4. WebThe green sphere is the radiation pattern of an ideal isotropic antenna that radiates the same maximum signal strength as the directive antenna does. The transmitter power that would have to be applied to the isotropic antenna to radiate this much power is the EIRP.
