摘　　要：本文设计和加工了一个L波段垂直极化全向天线和S波段水平极化全向天线,通过组合设计使得天线满足安装载体要求,其中L波段采用双锥天线,实测水平面不圆度小于1.3dB,增益大于2dB,驻波小于1.4,S波段采用波导缝隙天线,实测水平面不圆度小于3dB,增益大于2dB,驻波小于1.6。两个天线上下排布,安装在一个天线罩内,天线罩直径仅为70mm,工作互不影响。In this paper,an L-band vertically polarized omni-directional antenna and an S-band horizontally polarized omni-directional antenna are designed and fabricated.Through the combination design,the antenna can meet the installation requirements.A biconical antenna is used in the L-band.The measured variations in the azimuth plane is less than 1.3dB,gain more than 2dB,VSWR less than 1.4.A waveguide slot antenna is used in the S-band.The measured variations in the azimuth plane is less than 3dB,gainmore than 2dB,VSWR less than 1.6.The two antennas are arranged vertically up and down and installed in one radome.The radome diameter is only 70mm,the two antennas operate without interfering each other.
