摘要:
提出了一种紧凑型内置多频段的4G LTE手机天线,天线辐射体由一个倒“L”贴片和一个阶梯型的折叠微带线的耦合结构构成.天线有3个工作频段:694～1 110 MHz、1 690～2 310 MHz和2 480～2 860 MHz,涵盖了LTE/GSM/UMTS等目前无线通信服务中正在使用的频率,也即能够支持当前大部分的2G/3G/4G通信网络.该天线使用单极子和电磁耦合的结构来实现多谐振点和大宽带,整个天线是印刷在介电常数为4.4的FR-4介质基座上,天线体积仅有40 mm×12.5 mm×5 mm,全向性的水平方向图、良好的增益和效率以及小型化的设计使得该天线在各类4G LTE移动终端上具有良好的应用前景.
Abstract:
An internal multiband 4G LTE antenna that is composed of a coupled structure with an inverted-L patch and a step-shape forky strip is presented.The antenna has three operating bandwidths 694～1 110 MHz,1 690～2 310 MHz and 2 480～2 860 MHz to cover LTE/GSM/UMTS,therefore,the proposed antenna can support most current 2G/3G/4G wireless communication network services.The antenna utilizes monopole and electromagnetic coupling structures to realize multi-resonance and broadband,the limited volume of the antenna is only 40 mm×12.5 mm×5 mm which is printed on a same size of FR-4 support(FR-4; εr=4.4).Omnidirectional horizontal diagram,good gain and radiation efficiency and miniaturized size make the antenna very prospective in various 4G LTE mobile terminals.
