摘要
A dual-polarization conversion transmitarray is proposed for a circularly polarized (CP) transmitarray antenna. The designed transmitarray realizes the polarization conversion and gain enhancement for the circular polarization incident wave. The transmitarray can transform the left-hand circularly polarization (LHCP) wave and the right hand circularly polarization (RHCP) wave into RHCP and LHCP waves, respectively. Two CP patch antennas are designed as source antennas to illuminate the transmitarray and form the transmitarray antenna. The experimental and simulation results show that the designed transmitarray realizes the polarization conversation and the gain enhancement for two CP antennas indeed.
