一种全面屏智能手机天线设计

Antenna design for a full-screen smart mobile phone

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

This paper proposes a full-screen smart mobile phone antenna and achieves bandwidths of 700--960 MHz, 1 710--2 170MHz, and2 500-2 700MHz. The size of the designed mobile phone simu- lation 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.
