A center feed reflectarray antenna is presented in this paper. Reflectarray antenna surface consists of the single layer unit cells. Each unit cell has a circular ring and a double square. Dimensions of the unit cells are selected such that a progressive phase shift is achieved at each unit cell. The Proposed reflectarray antenna has a gain of 30.86 dBi at 18 GHz. The designed antenna shows good performance in terms of gain and phase range. This makes our antenna design simple, cost-effective and lightweight as compared to other single layer reflectarray antennas.
