【摘要】 为了满足5G移动通信的日益发展需要,本文提出了一款Sub-6GHz与毫米波双频段共口径手机终端天线.该天线由Sub-6GHz环天线与毫米波振子天线构成.低频环天线位于边框外侧,高频振子天线位于手机边框内侧.利用低频环天线的几何结构实现共口径设计.仿真结果表明,环天线-6dB阻抗带宽为3.44～3.59GHz,振子天线-10dB阻抗带宽可以覆盖5G n257频段(26.5～29.5GHz),各端口隔离度都优于-12dB.该共口径天线紧凑地置于手机边框,节约了手机内部空间.更多还原

【Abstract】 To meet the development needs of 5 G mobile communications,a Sub-6 GHz and millimeter wave dual-band shared aperture mobile terminal antenna is proposed.The antenna is composed of Sub-6 GHz ring antenna and millimeter wave monopole antenna.The ring antenna is located outside the frame,and the monopole antenna is located inside the frame of the phone.The geometric structure of the ring antenna is used to achieve a shared aperture design scheme.The simulation results show that the impedance bandwidth of ring antenna-6 dB is 3.44～3.59 GHz,and the impedance bandwidth of monopole antenna can cover 5 G n257 band(26.5～29.5 GHz),and the isolation degree of each port is higher than that of-12 dB.The shared aperture antenna is compact in the frame of the mobile phone,saving the internal space of the mobile phone.更多还原
