Omnidirectional antennas attempt to radiate equally horizontally. An isotropic antenna radiates equally in all directions but is only theoretical. All antennas have some gain.

That being said, there are some antennas that attempt to minimize that gain and be as non-directional as possible while other antennas attempt to maximize that gain and become as directional as possible.
