Abstract:
The beamforming technique is an important factor in designing modern wireless communications systems. While Rotman lens is a vital method to achieve the ability to steer the radiation pattern at the desired locations. Besides, there are many contributions to enhancing the performance of such lens, however, a classification to review this development is required. The main objective in this study objective is to explain and discuss the historical evolution of the Rotman lens as a beamformer based on the simulation methods used to analyze the mathematical model of the Rotman lens. The study shows that the variety of the methods is to achieve accurate simulation results while the simulation time and hardware computer requirements are still a challenge.
