一种全面屏智能手机天线设计

Antenna design for a full-screen smart mobile phone

摘要: 提出一种适合在全面屏手机终端上使用，带宽为700~960 MHz、1 710~2 170 MHz、2 500~2 700 MHz的手机天线.设计的手机仿真模型的长宽高尺寸为158 mm×77 mm×7.5 mm，手机天线的长宽高尺寸为70 mm×5 mm×4 mm，其天线效率分别为20%~35%（700~960 MHz）、20%~55%（1 710~2 170 MHz）、25%~35%（2.5~2.7 GHz）.在目前全面屏天线净空区域3.5 mm的情况下，天线的辐射效率能够满足设计要求.

Abstract: This paper proposes a full-screen smart mobile phone antenna and achieves bandwidths of 700-960 MHz, 1 710-2 170 MHz, and 2 500-2 700 MHz. The size of the designed mobile phone simulation model is 158 mm×77 mm×7.5 mm, and the size of the mobile phone antenna is 70 mm×5 mm×4 mm. The antenna efficiency of 700-960 MHz is 20%-35%, that of 1 710-2 170 MHz is 20%-55%, and 2.5-2.7 GHz is 25%-35%. When the width of antenna clearance area is only 3.5 mm, the radiation efficiency of the antenna can meet the design requirements.
