Abstract

Concept of Orbital Angular momentum with the help of mathematical equations has been discussed. An investigation of 4, 6 and 8 elements uniform circular array (UCA) for different Orbital Angular Momentum (OAM) modes is carried out. The effect of varying the uniform circular radius is also disused. The application of OAM in microwave frequency to enhancing the channel capacity is discussed. Uniform circular antenna array for all possible combination has been simulated and its results are demonstrated for different physical and electrical characteristic
