The printed antennas are good candidates for wireless systems, because of its advantage of low cost, low profile and easy to integrate to MMIC. Recently, researchers have attracted the dualband and the multi-band antennas for wireless applications. Wireless local area network (WLAN) technology is a wireless communication standard, which covering the lower band from 2.4 to 2.484 GHz (IEEE 802.11b/g) and the higher band from 5.15 to 5.825 GHz (IEEE 802.11a). In order to apply to the WLAN systems, many printed monopole antennas have been proposed in the literature [1-8]. Such as CPW-fed tapered bent folded monopole antenna [1]. In [2-3], the microstrip-fed printed monopole antenna. In [4], Dual-band Hybrid Antenna is proposed for WLAN application. In dual-band antenna is proposed using a parasitic plate for WLAN applications [5-8]. In this paper, we propose an antenna design with a low-complexity and a small size for Wireless LAN systems. Compared to [5-8], the proposed antenna has advantage of small antenna size, broad impedance bandwidth and simple structure. In the further, the dual-band characteristic of the monopole antenna is forming by using a parasitic plate under a rectangular patch. Details of the proposed antenna configuration and experimental results are discussed.
