摘　　要：为了满足移动通信室内基站和小区美化的需求,文中根据槽式天线理论、几何绕射理论和旋转场理论设计了一种双频槽式水平全向天线.该天线由4个宽频带槽式天线、双锥赋形反射器和功分器组成,天线有效压缩垂直面的辐射方向图,从而提高天线的增益.实验结果表明,该天线有较佳的辐射特性和较高的增益,能满足宽带、双频、多频无线通信的需求,并对工程上设计水平全向天线有一定的指导意义.To meet the requirements of building the indoor base station and beautifying the environment of district wireless communications, a dual-band tapered slot horizontal omni-directional antenna was proposed experimentally based on tapered slot antenna theory, geometrical theory of diffraction and rotating field theory. The proposed antenna is composed of four wideband tapered slot antennas, one dual cone reflector and power divider. The radiation pattern in vertical plane is compressed and thus a higher gain is obtained. The experimental results show better radiation and higher gain. The antenna can be applied to wideband, dual-frequency, and multi-frequency wireless communications. The proposed antenna can offer practical guidance to engineering application.
