摘要:

提出了一种新型的用于WLAN/WiMAX通信系统的双频带印刷单极天线。通过改进的叉子形的辐射贴片,使天线在2.4 GHz频带内谐振。同时,在介质基板背面的引入寄生辐射贴片,利用与正面的辐射贴片的耦合效应,使天线谐振在5 GHz频带内。最终使得天线可以覆盖2.4/5.2/5.8 GHz WLAN 和5.5 GHz WiMAX频带。对加工后的天线模型测试表明,天线在工作频带内具有较好的全向辐射特性和可观的增益。因此,该天线在无线多频带通信系统中具有广泛的应用前景。

Abstract:

A novel microstrip-fed printed monopole antenna is proposed for WLAN and WiMAX applications.Using a modified fork-shaped strip,an impedance bandwidth covering 2.4 GHz WLAN band is obtained.In addition,a fork-shaped parasitic plane is inserted on the bottom of the FR4 substrate to cover 5.2/5.8 GHz WLAN and 5.5 GHz WiMAX bands.Omnidirectional radiation patterns with appreciable gains over the operating bands are obtained by the fabricated antenna.The antenna is suitable for multi-band wireless communication applications.

Key words: Multi band antenna;compact planar antenna;wireless communications;WLAN;WiMAX
