  In this paper, different generations of mobile communication have been
concisely mentioned. The need for advanced antenna systems capable of sending
and receiving massive data is felt in the fifth generation of mobile
communication. The beamforming method and multi-input multi-output systems
(MIMO) are the proposed solutions to increase the channel capacity of the
communication network. Orbital angular momentum (OAM), an inherent feature of
electromagnetic waves, is a suitable solution to increase channel capacity.
This feature will increase the channel capacity by producing orthogonal modes.
Using antenna arrays is an effective way to produce these modes. The results of
FEKO simulations show the capability of this method.
