Dual-band single layer microstrip reflectarray using multiresonance double cross elements

This paper has presented a multiresonance cross element which can be used to build a dual-band reflectarray with dual linear polarization. It has a single layer structure which makes it easy to manufacture. The results presented in this paper has shown that the mutual effect between the elements of the two bands is negligible, which makes it easy to achieve the phase compensation for each band separately.
