Design of High Gain Low Cost Beam-Steering Reflectarray Antenna
Design of a low cost and high gain reflectarray antenna is presented in this paper. A 28 × 28 element reflectarray surface has been designed for beam steering between -40° and +40° from the broadside. Unit cell of the reflectarray surface consists of a circular ring and a double square. The characteristics of the reflecting elements are selected such that a progressive phase shift is achieved. Beam steering can be achieved by switching between multiple feed antennas. Antenna shows a peak gain of 29.77 dBi at 18 GHz. In Comparison to the conventional beam steering antennas, the proposed antenna has higher gain and the design is cost effective to implement.
