Reflect Array Antenna with Isoflux Beam for Satellite Application

In this paper a low loss reflective surface for beam shaping with wide bandwidth is presented. In this reflective surface an orthogonal polarization is achieved with the use of a metallic symmetric unitcell. Simple fabrication, adjustment of reflective phase and low loss are the main advantages of this unitcell. With the use of this unitcell, a reflective surface with isoflux beam for satellite applications in X-band frequency is designed and the simulation and optimization results are presented. The bandwidth of the presented unitcell for designed beam is above the 120%.
