摘要
径向线缝隙天线(简称RLSA)是Ku波段卫星直播电视(DBS)地面接收天线,RLSA天线的高增益、高效率、小口径、厚度薄的平板型紧凑式结构,代表了DBS地面接收天线的发展趋势。本文论述了RLSA天线的结构特点,技术进展,并对口面场分布进行了分析。
A radial line slot antenna (RLSA) is a slotted waveguide planar array for direct broadcasting from a satellite (DBS) subscriber antennas of Ku band with high gain,high efficiency,small size,and structural simplicity,which is the development trend of antenna used for DBS.The article discusses the structural characteristis and the technique development of RLSA,and we have an analysis for distribution of electromagnetic wave.
