摘　　要：本文提出了一种线极化径向隙缝天线(RLSA)。这种隙缝天线最初用来接收圆极化直播卫星信号,效率很高。本文给出了新型的隙缝排列,使它能从旋转对称的引导波产生线极化的匀均的口面分布。文中还给出了这种天线基本特性的测试结果,从而验证其设计方法。A design for a linearly polarized radial line slot antenna(RLSA) is proposed.The RLSA was first developed to receive direct broadcastsfrom satellite by means of circular polarization.and its highefficiency characteristics have been reported.A novel slot arrangement is presented which couples tothe rotationally symmetric guided waves to produce a uniform aperture distributionwith linear polarization.The basic characteristics are measured,and the designmethod is verified.
