A Review on Orbital Angular Momentum With the Approach of Using in Fifth-Generation Mobile Communications

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.
