Abstract :
Design of a broadband center-fed single-layer reflectarray antenna is presented, in this paper. The elements of the reflectarray, are circular patches and rings. By optimizing the element, more than 600 degrees linear phase range is achieved at center frequency (18.5GHz). The maximum gain of this antenna is 30.8 dB with a 1-dB bandwidth of 14.6% and 3-dB bandwidth of 25%.
