Detailed explanation-1: -An isotropic antenna (also known as an omnidirectional antenna) emits the signal uniformly in all directions.
Detailed explanation-2: -An Omni-Directional antenna radiates and receives the RF energy equally, providing a 360 degree radiation pattern which allows connectivity in all directions. A Directional Antenna has a radius of around 45 to 90 degrees, focusing RF energy in a required direction and limiting connectivity to that particular area.
Detailed explanation-3: -An omnidirectional antenna is described as having a radiation pattern that is relatively the same in all directions within a single plane (i.e. horizontal x-y plane). Conversely, a directional antenna has less of a symmetrical radiation pattern, with most of its radiated energy concentrated in a single direction.
