【摘要】 为了满足5G及未来手机终端发展中对天线的需求,提出了一种基于缝隙和环结构的双频段共口径手机天线.低频段天线基于缝隙结构设计,高频段天线采用环结构设计,两种天线设置在手机模型长侧介质板上.仿真结果表明,天线可工作在sub-6GHz和毫米波频段,天线在低频段有两个谐振点,工作带宽为2.85～3.18GHz、4.00～4.21 GHz,在高频段的工作带宽为23.82～25.61 GHz (S11<-10dB).该天线具有结构紧凑、制作简单、拥有较好增益的特点,任何端口之间的隔离度均优于10dB,为移动终端天线提供了一种新型设计方案.更多还原

【Abstract】 In order to meet the demand for antennas in the development of 5 G and future cell phone terminals,a dual-band common aperture cell phone antenna based on slit and ring structures is proposed.The low-frequency band antenna is designed based on the slit structure,and the high-frequency band antenna adopts the ring structure design,and the two antennas are set on the long-side dielectric plate of the cell phone model.The simulation results show that the antenna can work in the sub-6 GHz and millimeter-wave bands,and the antenna has two resonance points in the low-band with the operating bandwidths of 2.85-3.18 GHz and 4.00-4.21 GHz,and the operating bandwidths of the high-band are 23.82-25.61 GHz(S11<-10 dB).The antenna is characterized by compact structure,simple fabrication and good gain,and the isolation between any ports is better than 10 dB,which provides a new design scheme for mobile terminal antenna.更多还原
