A new dual-band antenna for WLAN applications

The IEEE 802.11 group has been established as the standard in wireless local-area network (WLAN). We propose a new design, which utilizes two different resonators to produce two resonant frequencies. One is the conventional inverted-L monopole for higher operating band, and the other is a half-wavelength open-loop resonator for lower operating band. The resultant bandwidth at the higher operating frequency band is approximately 1 GHz. This bandwidth is broad enough to provide whole IEEE 802.11a operation. Details of the proposed antenna design considerations and experimental results are presented.
