摘要：

A microstrip reflectarray antenna is a flat. reflector antenna, which consists a thin reflecting surface. made up of many individual elements and an illuminating feed. This kind of antenna has many good characteristics than traditional parabolic reflectors, such as low profile, easily deployable, lower manufacturing cost and scannable beam. A 260mm-diameter microstrip reflectarray antenna is designed by using MOM-based commercial EM software FEKO. The maximum right hand circularly polarization gain is 19dB and the sidelobe level is -18dB at 8GHz. The aperture efficiency is 40% and the circular polarization axial ratio is 2dB.
