【摘要】 在通信领域,反射面天线是常用的天线形式,具有增益高、性能稳定可靠等特点。但是反射面天线尺寸大,并且需要复杂的伺服跟踪系统,因此不适合车载、机载等安装平台。相控阵天线具有低轮廓、易共形、跟踪速度快等特点,是通信天线的技术发展趋势。一维相控阵天线是一种俯仰电扫描、方位机械扫描的天线形式,具有外形低、跟踪速度快、复杂度和成本较低等优点,可作为高性能的通信天线。更多还原

【Abstract】 In the field of communication,the reflector antenna is the common antenna,which has the characteristics such as high gain and good performance.However,the reflector antenna has a big size and needs a complicated servo Tracking system,so it is not suited for installation platform of vehicle and airborne.The phased array antenna has the features such as low profile,good conformal shape and high tracking speed,it is the development trend for communication antennas.The one-dimensional phased array antenna is a kind of antennas with pitching electrical scan and azimuth mechanical scan,which has the advantages of low profile,good conformal shape,high tracking speed and low cost and low complexity.In a word,it can be used as high performance communication antenna.更多还原
