Abstract: An offset-fed reflectarray antenna composed of single-layer elements based on the combination of circular and square concentric rings of variable size is presented in this paper. The characteristics of the elementary cells have been optimized providing a lineal phase curve with a phase range higher than 360°. The 297 × 297 mm reflectarray has been designed, fabricated, and measured to operate at 16 GHz and radiates the main beam in the direction given by θ = 10° and = 0°. In spite of utilizing a thin substrate, measured results of the linearly polarized reflectarray demonstrate a 1 dB gain bandwidth of 15.48% and radiation efficiency of 52.36% with a peak gain of 32.21 dB. Also, the measurements exhibit a cross-polar discrimination better than 27 dB in the working frequency band.
