摘要
A new method to design ultra-thin high gain circularly polarized lens antenna system with high efficiency is proposed based on the transparent focusing metasurface. The rotated method is utilized to compensate the phase deviation of circularly polarized wave and a focusing transmission lens working at Ku band is well optimized. For further application, an ultra-thin single-layer transmissive lens antenna operating at 13GHz is implemented. The simulation results indicate that the antenna system advances in many aspects such as a high gain of 17.6dB, the axis ratio better than 2dB, a high aperture efficiency of 41% and also a simple fabrication process. The good performance of the proposed antenna indicates promising applications in portable communication systems.
