摘要：

提出了一种新型的应用于4G通信的小型多频手机天线. 利用折叠单极子、多枝节谐振等技术使天线谐振在多个频段. 天线结构紧凑(32 mm×15 mm×0.8 mm), 由两个折叠单极子组成, 长度均约为1/4谐振波长, 其中倒C形枝节谐振在2 GHz附近, 倒F形枝节谐振在900 MHz附近. 天线通过50 Ω 匹配传输线直接馈电, 两个枝节共同叠加耦合辐射,实现带宽810 971 MHz和14 952 786 MHz, 覆盖了GSM 850/900/DCS/PCS/UMTS/LTE 2300/2500频段, 符合4G通信手机天线的标准. 对天线进行了加工和测试, 测试结果与仿真结果基本吻合.

Abstract:

A novel compact multiband mobile phone antenna for 4G communication is proposed. Using meandered monopoles and multiple branches, the antenna can resonate in multiple bands. The antenna is compact in size 32 mm×15 mm×0.8 mm. It consists of two meandered monopoles both having a length of about 1/4 wavelength. The C-shaped strip resonates at 2 GHz and the F-shaped strip at 900 MHz. The antenna is directly fed by a 50 Ω matching transmission line. The two strips co-radiate by combining and coupling to each other to achieve bandwidth of 810 971 MHz and 14 952 786 MHz, covering GSM 850/900/DCS/PCS/UMTS/ LTE 2300/2500 and meeting the requirements of mobile phone antenna for 4G communication. A prototype is fabricated and tested, showing general agreement between simulation and measurement results.
