【摘要】 提出了一种应用于WLAN/WiMAX的新颖的多分枝单极天线,天线有三个分枝,结构紧凑,其大小为26mm×24mm×1.6mm,加工出了天线并进行测试,测试结果表明天线具有良好的双波段工作特性,|S11|≤-10dB时对应中心频率2.47GHz和4.825GHz处带宽分别达4%和62.4%,覆盖WLAN的2.4/5.2/5.8GHz频段及WiMAX的3.5/5.5GHz频段,同时采用了接地板开槽技术以调整带宽,天线在上述频段有近似于全向辐射方向图。更多还原

【Abstract】 A design scheme of a novel multi-branch monopole antenna for WLAN/ WiMAX application is presented in the paper.The proposed antenna with 3-branch is compact with a total size of 26 mm×24 mm×1.6 mm.A prototype is constructed and tested.The test results show good dual band operations with |S11| ≤-10 dB impedance bandwidth of 4% and 62.4% centered at 2.47 GHz and 4.825 GHz respectively,which cover both the WALN bands in 2.4/5.2/5.8 GHz bands and the WiMAX 3.5/5.5 GHz bands.A new technique of using a slot in the ground plane has been employed to achieve the multiband performance of the antenna.The proposed antenna exhibits nearly omnidirectional radiation patterns for the bands.更多还原
