摘要
通过在接地板进行开槽和切角,辐射贴片挖槽实现对天线带宽进行扩展,在辐射贴片上添加谐振环和长方形的组合枝节实现Wi-MAX波段的陷波特性;在接地板开2个对称的L形状的槽实现WLAN波段的陷波特性;在辐射贴片刻蚀4个规则矩形槽来实现X波段的陷波特性。在Ansys HFSS15.0中建模仿真并作出实物,通过矢量网络分析仪进行验证,天线在2.3~13.3 GHz的频段内能够正常的工作。
The antenna bandwidth is expanded by slotting and chamfering the ground plate and slotting the radiation patch.The combination of resonant ring and rectangular branch is added to the radiation patch to achieve the notch characteristics of Wi-MAX band.Two symmetrical L shaped slots are opened in the ground plane to realize the notch characteristics of WLAN band.Four regular rectangular grooves are etched on the radiation patch to achieve notch characteristics of the X-band.Modeling and simulation are carried out by Ansys HFSS15.0,and real object is made.It is verified through the vector network analyzer that the antenna can work normally in the frequency band of 2.3~13.3 GHz.
