A wide open slot antenna with a pair of symmetrical L-strips for dual-band WLAN applications is proposed in this paper. A T-shaped monopole is used to cover 5.15~5.825 GHz. To achieve dual-band characteristic, a pair of symmetrical L-strips is embedded in the wide open U-slot to generate another band covering 2.4~2.48 GHz. The two bands are relatively independent from each other. The proposed antenna has the advantages of simple structure and excellent performance on the WLAN 2.4/5.2/5.8 GHz bands. The measured results of the fabricated antenna show that the impedance bandwidths are 150 MHz from 2.37 to 2.52 GHz and 1270 MHz from 4.83 to 6.10 GHz, which cover all the desired operating bands. Furthermore, the antenna design and some significant parametric studies are also described in detail.
