摘要 随着LTE在移动宽带服务中的使用,平板电脑等移动终端满足移动通信宽带化的需求日益迫切。设计了1个用于平板电脑的小型化LTE/GSM/UMTS多频段天线。天线尺寸只有15 mm×40 mm×0.8 mm。针对超薄平板电脑中平面倒置F型天线的高度要求难以实现,通过引入T型驱动单极子结构,有效降低了天线高度;通过嵌入并联谐振螺旋电感展宽了低频段(850 MHz^910 MHz)带宽;通过加载缺陷地结构展宽了高频段(1 710 MHz^2 690 MHz)带宽。天线覆盖GSM850/900/1800/1900/UMT2100/LTE2300/2500频段,同时天线增益也满足平板电脑的要求。 With the rapid employment of LTE in mobile broadband services, the requirements of broad bandwidth for mobile terminals, such as tablet computer, are increasingly urgent. A miniaturized multi-band antenna(15 mm×40 mm×0.8 mm) employed in LTE/GSM/UMTS is designed, which can be applied to tablet computers. A T-shaped driven monopole structure is introduced in order to reduce the effective height of PIFA(Planar Inverted F-shaped Antenna) used in ultra-thin tablet computer. The low band(850 MHz-910 MHz) is extended by embedding a parallel-resonant spiral inductor. The high band(1 710 MHz-2 690 MHz) is extended by loading a Defected Ground Structure. The antenna covers the bandwidth of GSM850/900/1800/1900/ UMT2100/LTE2300/2500, and the gain of the antenna also meets the basic requirements of a tablet computer.
