可用于移动终端的电感加载宽带电小单极天线

内容简介：为满足新型无线通信系统中移动终端天线对小型化宽频带的要求,设计了一种平面单极天线,通过加载贴片电感实现了小型化,通过双谐振实现了宽频带。实测结果表明,该天线辐射体自身尺寸仅为0.066λ0×0.048λ0×0.005λ0,远远小于工作波长,且可完全覆盖LTE band 14(758MHz~798MHz)、GSM 850(824MHz~894MHz)以及GSM 900(890MHz~960MHz)等频段,辐射效率良好。此外,还借助结构的关键参数分析对天线设计的原理进行了较详细的说明。

Abstract：A planar monopole is designed for novel mobile terminals in wireless communication system. Inductors are loaded for the miniaturization and dual-resonance is introduced for band-width enhancement. The measured results show that the size of the radiator is as small as 0. 066λ0 ×0. 048λ0 ×0. 005λ0 , which is far below the wavelength. Several bands including LTE band 14 ( 758 MHz ~798 MHz ) , GSM 850 ( 824 MHz ~894 MHz ) and GSM 900 ( 890 MHz ~960MHz) are completely covered. The design principle of such an antenna is explained with the help of analysis of some key parameters as well.
