摘 要: 研究设计了一款应用于手机通讯的紧凑型多频段内部手机天线。该天线结合了耦合馈电方案和磁电介质材料,通过加载铁氧体和MF-112两种材料,并利用天线枝节的合理布局和参数优化,使天线的尺寸保持在35 mm×12 mm×3 mm. 在实现小型化的同时,也使天线保持了极好的宽频特性,带宽0.69~0.96 GHz、1.44~2.87 GHz,覆盖了手机通讯的LTE 700/GSM 850/900/1800/1900/UMTS 2100/LTE 2300/LTE 2500八个频段。与传统天线设计手段相比,该天线具有容易加工、带宽较宽的优点,在手机网络中具有广阔的应用前景。

Abstract: A compact multi-band internal mobile phone antenna for mobile communication is designed in this paper. The antenna combines the coupling feeding scheme and the magnetoelectric material. By loading ferrite materials and MF-112, and using the reasonable layout of the antenna branches and the optimizing parameters, the size of the antenna is maintained at 35 mm×12 mm×3 mm. While achieving miniaturization, it also maintains excellent broadband characteristics. The bandwidth is 0.69-0.96 GHz and 1.44-2.87 GHz. It covers eight bands of LTE 700/GSM 850/900/1800/1900/UMTS 2100/LTE 2300/LTE 2500 for mobile communication. Compared with traditional antenna design methods, it has the advantages of easy processing and wide bandwidth, which has broad application prospects in mobile network.
