Abstract

A multiband coupled on-board printed handset antenna capable of providing wideband operation for GSM 1800/1900, UMTS and LTE 2300/2500 is presented. Antenna consists of coupling monopole resonators which are extended from the feed and main ground plan to accommodate integration with circuit board of mobile handset. Antenna can easily be fabricated with the help of extended line and ground without disturbing main circuit board of handset, considering the presence of protruded components over circuit board. The antenna design uses fork-shaped monopole coupling resonators extended from active element and ground plane. These resonators along with prolonged length from patch and ground, as a function of resonating wavelength, control the bandwidth of antenna. Monopoles driven from patch and ground contribute the lowest and higher order resonant modes to form three wide operating bands centered at about 1800, 2500 and 5200MHz to cover GSM1800/1900/UMTS/LTE2300/2500. The results of this study confirmed that extended planner monopoles couple to form lower and higher resonant modes. This study provides new understanding on coupling monopole resonators and their application in handset antenna designing.

带有耦合单极子的车载印刷手机天线

提出了一种多频带耦合的机载印刷手机天线，可为GSM 1800/1900、UMTS和LTE 2300/2500提供宽带服务。天线由耦合单极谐振器组成，这些谐振器从馈线和主地平面延伸出来，以适应与手机电路板的集成。考虑到电路板上存在突出的组件，可以很容易地利用延长线和地线制作天线，而不会干扰手机的主电路板。天线设计采用叉形单极耦合谐振器，从有源元件和地平面向外延伸。这些谐振器以及从贴片到地的延长长度作为谐振波长的函数，控制着天线的带宽。从贴片和地驱动的单极子贡献了低阶和高阶谐振模式，形成了以1800、2500和5200MHz为中心的三个宽工作频段，覆盖了GSM1800/1900/UMTS/LTE2300/2500。本研究的结果证实了扩展规划单极子耦合形成低、高共振模式。本研究对耦合单极谐振器及其在手机天线设计中的应用提供了新的认识。
