一种新型电感加载宽频带GSM3GWIFI单极天线

内容简介：设计了一种采用感性加载方式的工作于0.8~2.5 GHz的宽频带GSM/3G/WIFI单极子天线，通过仿真和实际测试发现这种加载方式在实现了良好阻抗匹配的情况下对天线方向图无明显影响。该天线具有全频段内增益高，方向图良好，阻抗频带宽的特点，由于采用了感性加载的阻抗匹配方式，实现了直流接地雷电防护功能，非常适合安装于机载环境。

Abstract：A novel inductance loading broadband GSM/3G/WIFI monopole antenna covering 0.8~2.5 GHz was designed. The simulation and actual test results indicates that the loading mode has no obvious effect on antenna directional pattern while it has good impedance matching. The antenna has the characteristics of high full-band gain,good directional pattern and wide impedance band. The antenna with inductance loading technique provides lighting protection with DC ground,and is suitable for airborne applications.
