摘　　要：提出并制造一种应用于WLAN、WiMAX和5G系统的紧凑型共面波导(CPW)馈电三频天线。为了实现三频工作,分别将两个条带与主辐射矩形贴片和共面波导地面相结合。天线印刷在1.6 mm厚的FR-4基板上,整体尺寸仅为20 mm×30 mm×1.6 mm。天线实测和仿真测试有良好的吻合性,矢量网络分析仪测试结果表明,该天线在2.22~2.56 GHz、3.32~3.70 GHz和4.69~7.39 GHz内回波损耗小于-10 dB,在工作频段内有良好的增益。相比其他多频天线,该天线结构紧凑、简单。A new compact coplanar waveguide(CPW)-fed tri-band antenna is presented and fabricated for WLAN,WiMAX and 5 G system.In order to realize three frequency operation,the antenna combined two strips with the main radiation rectangular patch and the coplanar waveguide ground respectively.The antenna was printed on 1.6-mm-thick FR-4 substrate and had a small overall dimension of only 20 mm×30 mm×1.6 mm.The measured and simulated result of the proposed antenna have good agreement.The vector network analyzer test shows that the propose antenna has three operating bandwidths,including 2.22-2.56 GHz,3.32-3.70 GHz,and 4.69-7.39 GHz,which have a return loss of less than-10 dB.The antenna has good gain in the operating band,and it is compact and simple compared with other multi-frequency antennas.
