摘要

提出了一款新型的小型化八频段手机天线,该天线由梯形馈电单元、耦合枝节组成,通过曲流技术以及电感加载缩小天线尺寸,天线尺寸仅为37mm×7.2mm×0.8mm。整个天线被印刷在C型FR-4基板上,采用同轴馈电。测试结果表明:所设计的天线能够覆盖LTE/WWAN八个频段,频段内S11小于-6 d B。实测结果与仿真结果吻合较好,天线结构新颖、体积小,在无线通信中具有良好的应用前景。
A novel miniaturized mobile phone antenna with octa-band is presented. The proposed antenna mainly consists of trapezoid feeding elements and coupling strip, which is printed on the C-shaped FR-4 substrate and is fed by a coaxial cable. Meander and inductor-loaded technologies are used to reduce the size. The size of the antenna is only 37×7.2×0.8mm~3. The measured results show that LTE/WWAN can be covered by the proposed antenna with S_(11) less than-6d B. A good agreement between measurement and simulation is achieved. The proposed antenna's structure is novel and compact, so that it has the good prospects for the wireless communication applications.
