Transformation optics has emerged as a useful tool to control the behaviour of electromagnetic fields and thus offers potential for designing novel antenna structures. In this contribution, a new antenna system based on a slim flat Luneburg lens located above a radiating source printed on a ground plane is proposed. The permittivity map of the transformed lens able to convert the nondirective beam radiated by a single source to a highly-directive beam with low side-lobe level is calculated. Numerical simulations based on CST Microwave Studio are performed to illustrate the proposed antenna system performance in comparison with a common Fabry-Perot cavity antenna. Results confirm the high-directivity, low side-lobe level and steering capability of the proposed antenna.
