A dual-wideband antenna with an open L-slot for wireless local area network (WLAN)/worldwide interoperability for microwave access (WiMAX) applications is proposed.A rectangular radiator with an open L-slot etched on the ground is used to cover 2.4 similar to 3.69 GHz. To achieve dual-band characteristic, a rectangular strip is inserted on the rectangular radiator horizontally to generate another band covering 5.15 similar to 5.85 GHz. The two bands are relatively independent with each other. Experimental results show that the antenna can operate at two separate impedance bands (S11<-10 dB) of 1330 MHz (2.37 similar to 3.70 GHz) and 1140 MHz (4.95 similar to 6.09 GHz), which can cover all the 2.4/5.2/5.8 GHz WLAN bands and the 2.5/3.5/5.5 WiMAX bands. Detailed design steps and experimental results are studied and investigated in this article.
