Abstract

This paper describes a novel Ku/Ka band reflectarray antenna for operating at arbitrary polarization. The reflectarray elements consist of two different types of elements: cross-dipole element with fixed-dimension ring for the lower band, and the ring element with round patches for the upper band. Furthermore, the parameters of the element are optimized to suppress the coupling effects. The simulated radiation patterns of the dual-reflectarray antenna using the proposed element can show a gain of 18.5 dB at 16 GHz and 24.9dB at 35GHz with the aperture efficiency of 38.21% and 34.85% for the lower and upper band, respectively.
