Abstract :
This paper presents a single-layer dual-band reflectarray, with identical polarization in two closely separated bands, and the ratio of the center frequencies is equal to 1.5. The phase delays can be controlled by four degrees of freedom of the element to simultaneously match the desired values at two center frequencies. A 6 × 10 reflectarray operating at 9GHz and 13.5GHz with a scattering angle of 30° for normal incidence of plane waves is designed to validate the availability.
