摘要
提出一种带有金属边框的LTE/WWAN/5G频段手机天线,该天线由金属边框与地板构成的缝隙天线结构、馈电枝节与边框构成的IFA天线结构、连接在地板上的单极子天线结构等组合而成。将金属边框作为天线的一部分,极大地缩小了天线占有介质基板的面积,使得介质基板上净空面积减小到65mm×5mm,而5mm地板窄净空宽度有利于天线应用于高屏占比的手机。测试结果表明,所设计的天线回波损耗在-6dB以下的频带范围能够有效覆盖LTE700/2300/2500、GSM850/900、UTMS2100、DCS1800、PCS1900以及3.5GHz频段,同时各相应频段上天线的辐射方向图、效率与增益也均能够满足手机天线的使用要求。
An antenna with a metal rim for LTE/WWAN/5Gband mobile phones was proposed. The antenna was composed of a slot antenna structure formed by the metal rim and the ground,an IFA antenna structure with a feeding branch and the rim,and a monopole antenna structure connected to the ground.The metal rim was used as a part of the antenna.Thus,the antenna area on the dielectric substrate is greatly reduced,and the ground clearance area is only 65mm×5mm.The narrow ground clearance width of 5mm is beneficial for the antenna application in high screen-to-body ratio phones.Measured results reveal that the proposed antenna can effectively operate in LTE700/2300/2500,GSM850/900,UTMS2100,DCS1800,PCS1900,and 3.5GHz frequency bands under-6dB return loss.The radiation patterns,efficiencies,and gains of the antenna in the corresponding frequency bands can meet the requirements of mobile phone application.
