摘要
提出一种应用于2.4/5.2/5.8 GHz WLAN和2.5/3.5/5.5 GHz WiMAX共面波导印刷单极子天线。该天线结构紧凑,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的微带传输线通过共面波导馈电的方式对具有对称结构的蝶型贴片馈电。在设计中,通过开缝和添加倾斜微带条,使天线获得的阻抗带宽可以覆盖WLAN和WiMAX频段。天线的总体尺寸为30 mm×32 mm,其结构紧凑、便于集成和加工,适合无线通讯应用。
A novel compact dual-frequency printed monopole antenna for 2. 4 /5. 2 /5. 8 GHz WLAN and 2. 5 /3. 5 /5. 5 GHz WiMAX applications is proposed. The antenna owns the feature of compact operation and can be easily integrated into most wireless communication equipments. By combining the symmetrical bowtie patch,slot and angle-shaped strip,the antenna can achieve a wide impedance bandwidth covering WLAN and WiMAX,which is fed by a 50 Ω microstrip transmission line. The good gain over the operating bands has been obtained by the fabricated antenna with a compact size of 30 mm × 32 mm,which is suitable for wireless communication applications.
