摘要：
A novel single-layer reflectarray element with three resonances, showing a linear phase curve and a large phase variation range over 800 degrees 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 x 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. (c) 2014 Wiley Periodicals, Inc.
