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。
This paper presents a dual-band wireless local area network monopole antenna. The antenna can be easily implanted wireless communication devices, has strong practicality. This antenna is fed by a 50-ohm microstrip transmission line through a coupling feed to an S-type chip having a symmetrical structure. Antenna gain impedance bandwidth can cover wireless LAN 2.4 / 5.2 / 5.8. The overall size of the antenna is 20 mm × 34.5 mm, compact structure, easy processing, easy integration, suitable for wireless communication applications. The design of antenna and the influence of different parameters on antenna performance are given in this paper.
