Anti-collision radars help prevent car accidents by detecting obstacles around vehicles equipped with such systems. This task relies on a high-performance antenna, which can detect the obstacles efficiently around the care. In this paper, we investigate the design of multi-beam antennas by the technique of optical transformation. Analytical formulas of the permittivity and permeability tensors are presented for the metamaterial layer in the antenna. The designed multi-beam antennas are validated by full-wave simulations using the finite-element method. The proposed multi-beam antennas will be very useful in the intelligent traffic system.
