摘要：

A reflectarray that radiates linear or circular polarization (LP-CP) is proposed for multipolarization applications. The reflectarray consists of two double-layer dipole arrays that are orthogonally printed on both sides of the dielectric substrate. With a linearly polarized (LP) feeder, the antenna can transform the LP incident wave into a circularly polarized (CP) one. Both left-hand CP (LHCP) and right-hand CP (RHCP) waves can be obtained by rotating the LP feeder from the polarization angle of 45 to 135. In addition, LP radiation can also be obtained when the polarization angle of the feeder is 0 or 90. A 32 x 32-element reflectarray has been designed, fabricated, and measured. The measurements validate the simulated results. The 3-dB axial-ratio bandwidths obtained for the LHCP and RHCP cases are 16.3% and 16.8%, with peak gains of 30.8 dBi at 26.3 GHz, and 31.6 dBi at 26 GHz, respectively.
