摘要

本文主要介绍了一种双分支的多频手机天线,与以往单一结构的手机天线相比,该天线使用了两种基本结构,即电感耦合的单极子结构和容性耦合的环结构。这样的设计方式不仅使天线的辐射尺寸大大的减小,而且实现了多个通信频段的覆盖。天线仿真结果表明,低端实现了0.7 GHz-1 GHz,高端实现了1.7 GHz-2.7 GHz,同时辐射效率在高频部分达到了60%-90%。这些仿真的数据和天线的实测数据基本吻合。
A multi-band mobile phone antenna with dual-branch is introduced in this paper. Compared with the previous antenna, the antenna applies two simple forms, which are inductive coupling branch in monopole structure and capacitive coupling branch in loop structure. In this way, the radiant size of the antenna is greatly reduced and the working bands of the antenna are multiple. According to the simulation results, the antenna covers frequency range 0.7 GHz-1 GHz and1.7 GHz-2.7 GHz, while its radiation efficiency in the high band achieves 60%-90%.these data and measured data of the antenna are basically consistent.
