Abstract

The important factor increased the efficiency of the antenna to support the user in the current technology is necessary wide impedance bandwidth, high gain, and low back radiation. In this paper, the antenna composed of the curved strip electric dipole and the vertically-oriented short patch is presented. The magnetic dipole is placed to point in the direction perpendicular to ground plane at an angle of 45 degree, fed by r-shaped strip. The impedance bandwidth of 65.23% (SWR<2) from the frequency range of 1.69–3.06 GHz is obtained and the antenna gain of 9 dBi is found over the operating frequencies, which is stable gain.

一种利用磁电弯曲条偶极子的宽带天线
提高天线效率的重要因素是在当前技术中必须支持用户的宽阻抗带宽、高增益和低背辐射。本文提出了一种由弯曲条形电偶极子和垂直定向短贴片组成的天线。磁偶极子以45度角指向与地平面垂直的方向,由r形条馈电。在1.69 ~ 3.06 GHz频率范围内获得65.23% (SWR<2)的阻抗带宽,在工作频率范围内获得9 dBi的天线增益,为稳定增益。
