摘要
提出了一种适用于无线局域网(WLAN)和全球微波接入互操作(WiMAX)的新型三频印刷单极子天线。单极子天线印刷在相对介电常数为4.4的环氧树脂板(FR4)上,由钩形支路和不完整圆环组成,实现了阻抗匹配性能优良的三频运算,采用50Ω微带线馈电,尺寸紧凑,整体尺寸为16.5 mm×25 mm×1 mm。加工的天线实测回波损耗与模拟结果一致,在工作频段满足S_(11)<-10 dB的阻抗带宽要求,同时覆盖WLAN和WiMAX频段。另外,所提出的天线在两个波段都显示出良好的辐射特性和增益。
A novel three-frequency printed monopole antenna for wireless local area network(WLAN)and world wide interoperability for microwave access(WiMAX)is proposed.The monopole antenna is printed on an FR4 substrate with a relative permittivity of 4.4and consists of a hook-shaped branch and an incomplete circular ring to achieve triple band operations with superior impedance matching,which is fed by a 50-Ωmicrostrip line and has compact dimensions of 16.5 mm×25 mm×1 mm.The measured return loss is in agreement with the simulated ones and satisfies the impedance bandwidth requirements of S 11<-10 dB at operation bands,while simultaneously covering the WLAN and WiMAX bands.In addition,the proposed antenna shows good radiation characteristics and gain at the both bands.
