Design of Dual-band Microstrip Reflectar- Ray Using Single Layer Multiresonance Dou- Ble Cross Elements
نویسنده
چکیده
A multiresonance double cross element is used to design a dual-band reflectarray with dual linear polarization. The proposed element has a single conductive layer structure which makes it easy to manufacture. The results presented in this paper show that the mutual effect between the elements of the two bands is negligible. Hence, it is easy to achieve the phase compensation for each band separately. The simulated and measured results for an element designed to cover the Xand K-bands have confirmed the suitability of the proposed element to build a dual-band reflectarray.
