Abstract
In this paper is presented the implementation of a corner reflector antenna where the reflective metal plates are replaced by frequency selective surfaces, FSS, based on the four-arm star geometry. The projected antenna an aperture angle of 60° and operation at 4.0 GHz. The design steps are described and numerical and experiments. For the region within the aperture angle, the corner reflectors with metallic plates and FSS presented practically the same results. The differences between numerical and experimental results in the region outside the angle region are discussed and justified. It is concluded that the use of FSS as reflectors in the corner reflecting antenna is feasible, which is very interesting considering the characteristics of the material (low weight and reduced volume) and the simplicity of the of the FSS. In addition, the antenna proposed in this work is potentially attractive, since it is possible to use FSS reconfigurable and, therefore, if an active antenna is obtained.
