摘要：
A wideband and low-profile circularly polarized antenna using metasurface for WLAN or satellite communication applications is proposed. The proposed antenna consists of a planar slot coupling antenna with an array of metallic rectangular patches which can be viewed as a metasurface. The metasurface is utilized to adjust axial ratio (AR) for circularly polarized radiation and the slot is angled at 420 with respect to the feed-line. Furthermore, the proposed metamaterial-inspired antenna has a compact structure with a low-profile of 0.07 lambda(0) (lambda(0) stands for the free space wavelength at 5.25 GHz). Simulated results show that the -10 dB impedance bandwidth for the proposed antenna is 32.5% from 4.25 to 5.9 GHz, and 3-dB AR bandwidth is 18.5% from 4.9 to 5.9 GHz.
