【摘要】 本文提出一种新的关于无线通信终端天线比吸收率(SAR)的归一化评价方法,对环形天线、单极子天线、平面倒F天线以及基于复合左右手传输线结构的零阶谐振天线在LTE Band 7频段的SAR进行对比分析。通过将馈入到终端天线的输入功率按照回波损耗和辐射效率进行归一,从而更加客观地评价这四种天线在智能手机和无线数据卡终端两种平台上的SAR特性。更多还原

【Abstract】 In this paper,a new normalized evaluation method is proposed to compare SARs of four terminal antennas for wireless communication at LTE Band 7 including loop antenna,monopole antenna,PIFA antenna and zerothorder resonant antenna based on the composite left- and right-hands transmission line.By normalizing input power by return loss and radiation efficiency of terminal antennas,the SARs of these four antennas are reasonably analyzed on two platforms including smart phone and wireless data card terminals.更多还原
