The proposed antenna can cover WLAN and WiMAX bands. The two rings are arranged side by side and are etched on the back-side of a printed circuit board. The open ends of the left and right split rings are positioned on the up-left and down-right directions.
Experiments verify that the proposed antenna can produce a wide band circular polarization wave with 3dB axial ratio bandwidth of 46% (2.3GHz~3.7GHz). 10dB return loss bandwidth of the antenna is 45% (2.3GHz~3.7GHz) and the antenna gain is more than 1dBic within the overlapped return loss and axial ratio bandwidths.
KEYWORD: micro strip antenna, circular polarization.
