Abstract:

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 × 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.
