In this paper, we will be reviewing beam steering application using lens antenna. Various approaches are available for achieving beam steering of lens antennas for different applications and some of them will be reviewed here. In radar systems, beam steering is accomplished by switching the antenna element or changing the relative phase. Beam steering has major role for 5g due to the quasi optic layer. Beam steering can also be done by varying the refractive index. In most of these papers studies, we found out that beam steering overcomes the interference, improves gain, increases directivity and also save power. Wide angle is also achieved in lens antenna.
