In this paper, we propose the beam-steering system using Rotman lens antenna operating at 2.442GHz which is to replace an expensive phase shifter. The overall system consists of the transmission antennas, Rotman lens and switch box. Setting the initial design conditions, it was designed and fabricated satisfying the requirements. From the result tested in the anechoic chamber, it was found that the beam can be steered using Rotman lens in the anechoic chamber. We also visually checked the beam-steering by turning on the LED of the rectenna showing the real-time beam receiving.
