摘要

Dual-band antenna is very essential for multiple band communication systems like wireless local area network (WLAN) with lower and upper operating bands. In this paper, a dual-band antenna is proposed and analyzed for the WLAN applications. The proposed antenna fed by coplanar waveguide (CPW) consists of an L-shaped, reversed L-shaped strips and two inverted U-shaped loadings that are to implement the reactive characteristics. The reactive loadings can adjust the bandwidth and performance of the dual-frequency WLAN antenna that is verified by the simulation and measurement, respectively. The results demonstrate that the -10dB impedance bandwidth of the proposed dual-band antenna can cover the two WLAN frequency bands from 2.4 GHz to 2.484 GHz and from 5.15 GHz to 5.35 GHz, respectively. Moreover, the proposed antenna has omnidirectional radiation patterns at the two operating bands.
