双频WLAN印刷单极子天线

Dual Frequency WLAN Printed Monopole Antenna

文中提出一种应用于无线局域网双频印刷单极子天线。该天线可以方便地植入无线通讯设备中,有较强的实用性。此天线由50Ω的微带传输线通过耦合馈电的方式对具有对称结构的S型贴片馈电。天线获得阻抗带宽可以覆盖无线局域网2.4/5.2/5.8。天线的总体尺寸为20 mm×34.5 mm,结构紧凑,易于加工,便于集成,适合无线通讯应用。文中给出了天线的设计及不同参数对天线性能的影响。

A novel compact dual-frequency printed monopole antenna for WLAN application is proposed in this paper.The antenna owns the feature of practicability and can be easily integrated into wireless communication equipments.By combining symmetrical S-shaped strips and a coupling-fed plate,fed by a 50Ωmicrostrip transmission line,wide impedance bandwidths covering WLAN/2.4/5.2/5.8 is achieved.The structure of the proposed antenna is compact,fabricated and integrated easily with a size of 20 mm×34.5 mm,which is suitable for wireless communication applications.The effect of the different parameters on the antenna is given in this paper.
