摘要:
多输入多输出(multiple-input multiple-output,MIMO)技术在手机天线设计中,经常遇到辐射单元尺寸过大、电磁兼容、天线辐射全向性和天线辐射效率等问题,本文提出一种多频段MIMO陶瓷天线的结构来研究和解决上述问题。其中,陶瓷结构的介电常数为6.45,并附在金属贴片结构上作为辐射单元。所采用新型的陶瓷材料将为天线提供更宽的带宽,并且减小天线辐射单元设计的尺寸,其辐射单元的尺寸为32.5 mm×17 mm×2.8 mm。实际测量天线带宽为0.89~0.97 GHz和1.71~2.20 GHz,实现了双频段移动通信并且覆盖了GSM900、DCS1800、PCS1900和LTE1900等频段。该天线具有良好的全向辐射特性,适合手机天线的应用,同时该MIMO天线的耦合隔离度较低。实测天线效率在0.89~0.97 GHz频段为21.3%~28.3%,在1.71~2.20 GHz频段为24.3%~35.2%,基本满足手机天线应用设计的需求。新设计的MIMO天线在未来全屏手机使用上将有广泛的应用前景。
Abstract:
In the design of mobile phone antenna, multiple-input multiple-output (MIMO) technology often encounters problems such as excessive size of the radiating element, electromagnetic compatibility, antenna omnidirectionality, antenna radiation efficiency, etc.. A structure of multi-band MIMO ceramic antenna is presented in this paper solve the above problems. The ceramic structure has a dielectric constant of 6.45 and is attached to a metal patch structure as a radiating unit. The new ceramic material will provide a wider bandwidth for the antenna and reduce the design size of the antenna radiating element with a size of 32.5 mm×17 mm×2.8 mm. The actually measured antenna bandwidths are 0.89~0.97 GHz and 1.71~2.20 GHz, which realize dual-band mobile communication and cover bands such as GSM900, DCS1800, PCS1900 and LTE1900, etc. The antenna has good omnidirectional radiation characteristics and is suitable for the application of a mobile phone antenna. Meanwhile, the coupling isolation of the MIMO antenna is low. The actually measured antenna efficiencies are 21.3%~28.3% in the frequency band of 0.89~0.97 GHz, and 24.3%~35.2% in the frequency band of 1.71~2.20 GHz, which basically meet the requirements of mobile phone antenna application and design. The newly designed MIMO antenna will have broad application prospects in the use of full-screen mobile phones in the future.
