Abstract A single-layer wideband high efficiency reflectarray in Ku-band has been presented in this paper. A novel dual-resonant patch element approach has been analyzed and optimized to obtain good radiation performances within the operating frequency band. The phase shift range of 573° can be obtained with less steep linear phase shift curve. To compensate the differential spatial phase delays from the feed to the elements, the variable size technique has been utilized for obtaining required phase shifts. The reflectarray aperture has been designed, manufactured and measured. Measured results are in good agreement with the simulated ones. The measured gain of the reflectarray aperture at center frequency can reach 27.2 dBi, which is equivalent to aperture efficiency of 51.3%, and the 1-dB gain bandwidth of the aperture is 18.4%.
