摘要：

A dual-band X-/Military Ka-band (MKa-band) single-aperture reflectarray structure that transmits and receives at both MKa- and X-bands is introduced in this paper. Frequency selective surface (FSS) is used as the ground plane for the MKa-band reflectarray. A cascade configuration of FSS-backed reflectarrays is designed for each of the receive and transmit bands of MKa- band to reduce the coupling between the elements of these two bands when they are etched on the same substrate. Additional FSS's are implemented to further enhance the isolation between the bands. The MKa- band elements are located on top of the X-band reflectarray that is composed of elements etched on a perfect electric conductor (PEC)-backed ground plane. The reflectarray elements also convert circular to linear polarization which results in a simplified feed structure.
