Detailed explanation-1: -An isotropic radiator is an ideal antenna which radiates power with unit gain uniformly in all directions, and is often used to reference antenna gains in wireless systems.

Detailed explanation-2: -An antenna which radiates uniformly in all directions in three-dimensional space is called an isotropic antenna.

Detailed explanation-3: -An isotropic radiator is a theoretical point source of electromagnetic or sound waves which radiates the same intensity of radiation in all directions. It has no preferred direction of radiation.

Detailed explanation-4: -An omnidirectional antenna radiates radio wave power uniformly in all directions in one plane, with the radiated power decreasing against elevation angles above or below the plane, dropping to zero on the antenna’s axis, and producing a “doughnut-shaped” radiation pattern, as shown in Fig.

Detailed explanation-5: -An isotropic antenna is used as a reference antenna to evaluate antenna gain. Many antennas specify gain in dBi (decibels over isotropic), which is the power transmitted by an antenna in a specific direction, divided by the power transmitted by an isotropic antenna emitting the same total power.
