A novel single‐layer reflectarray element with three resonances, showing a linear phase curve and a large phase variation range over 800° is proposed for a broadband operation. Different size of elements are selected by using a simple guideline to achieve the required phase distribution in a given frequency band. Two offset‐fed 10 × 10 reflectarrays with different scattering angles are designed. Simulations and measurements show the bandwidth of 28% for a 3‐dB gain drop and 44% for −10‐dB side lobe level inspite of the large F/D of 2.1. © 2014 Wiley Periodicals, Inc.
