A novel single layer microstrip reflectarray element with multi-resonance structure is presented. The element is composed of six dipoles which are placed in parallel at a certain distance. The element has good linear polarization properties. Ansoft HFSS is used to optimize the parameters and linear reflection phase curves in two bands are achieved. A dual-band dual-polarization reflectarray composed of the elements is designed, fabricated and measured. The proposed reflectarray operates in two frequency bands within X band centered at 10 GHz and Ku band centered at 13.58 GHz. The reflectarray is offset fed by only one horn antenna for both bands in two orthogonal polarizations. Measured results show good radiation performance in both bands. A well coincide is obtained between the simulated and measured results, which demonstrate the desirable dual-band dual-polarization radiation performance of the reflectarray. The design is valuable to other reflectarray in achieving dual-band dual-polarization performance.
