A high gain circular polarization antenna with metamaterial slabs has been proposed. Metamaterial slabs having periodic circular lattices have been used to focus beam while fan-shaped patches are added on the slabs to generate circular polarization. The proposed antenna has shown a good axial ratio at the resonant frequency band. It also has shown a simulated gain improvement and transmission gain improvement by 12.1 dB and 20dB, respectively. In addition, the left/right handed polarization is simply controlled by turning over metamaterial slabs.
