一种应用于WLAN/WiMAX的宽带三频天线设计
|
摘要
设计了一款应用于WLAN/Wi MAX领域的具有三频特性的微带天线,同时覆盖了WLAN的2.4/5.8 GHz频段和Wi MAX的3.5/5.5 GHz频段。该天线通过四个半圆环和一个半圆形贴片以及微带线产生两个谐振频率,然后采用带有圆形凹槽的不规则矩形片激发了第三个谐振频率,同时改善了天线阻抗带宽。通过仿真结果表明,天线在三个频段处的回拨损耗均小于-10 d B,有较宽的带宽和良好的全向辐射特性。进行了加工和测试,测试结果与仿真结果大致吻合,具有一定的实用价值。
A broadband three-frequency antenna applied for WLAN/Wi MAX area is designed,which covers the2. 4 /5. 2 /5. 8 GHz frequency of WLAN and 3. 5 /5. 5 GHz frequency of Wi MAX. Two resonant frequency are produced through four semi-toroidal patches,a semicircle patch and microstrip line,then irregular rectangular is adopted with the circular-slot to inspire the third resonant frequency and improve the antenna impedance bandwidth simultaneously. Simulation indicates antenna in each frequency band has wide bandwidth and good omnidirectional radiation characteristics and return loss less than- 10 d B. Finally,the designed antenna is fabricated and measured. The measured results are in agreement with the simulated results and have some practical value.
