摘　　要：提出了一种改进型的应用于无线局域网的双频印刷单极子天线。该天线可以覆盖IEEE 802.11a/b/g（2.4~2.484GHz,5.15~5.825GHz）频段标准,其回波损耗小于10dB的阻抗带宽在2.4GHz频段可达290MHz（2.28~2.57GHz）,在5GHz频段可达5.53GHz（4.34~9.87GHz）。另外,在工作频带内,还获得了良好的全向辐射方向图和天线增益。该天线的总体尺寸为22mm×44mm,结构紧凑,且具有不圆度低、成本低和易于集成等优点,因此具有十分良好的应用潜质。A improved dual-band printed monopole antenna is proposed in this paper. The antenna can cover the working bands of IEEE 802.11 a/b/g （2.4 -2. 484GHz,5.15 -5. 825 GHz）. The impedance bandwidth are 290MHz in 2.4 GHz and 5.35GHz respectively with returnloss than 10dB. Also, good omni-direetional radiation patterns and antenna gain o- ver the operating bands have been obtained. The structure of the proposed antenna is compact and integrated easily with a size of 22mm×44mm. The antenna has a good potential application in WLAN system.
