    • PROBLEM TO BE SOLVED: To provide a lens antenna apparatus suitable for mounting on a mobile in which multibeam is realized through a simple and stable structure.
      SOLUTION: A guide rail 130 is laid in parallel along the circumferential surface of the hemispherical lens 120 in a hemispherical lens antenna 100 and a plurality of radiators 140-160 are located and secured onto the guide rail 130. Since the radio beams of the plurality of radiators are subjected to directivity control during operation by regulating an AZ axis rotary mechanism 220, an EL axis rotary mechanism 230, and an xEL axis rotary mechanism 240, a small, lightweight and high precision satellite tracking performance is realized inexpensively. Since no driving section exists on the guide rail 130, even a multibeam to an adjoining satellite does not interfere with the driving section and a plurality of radiators can be arranged. Consequently, multibeam is realized through a simple and stable structure and an arrangement suitable for mounting on a mobile is realized.

    • 要解决的问题:提供一种适于安装在通过简单且稳定的结构实现多波束的移动体上的透镜天线装置。 解决方案:导轨130沿着半球形透镜120的圆周表面平行布置在半球形透镜天线100中,并且多个散热器140-160被定位并固定在导轨130上。由于无线电波束 通过调节AZ轴旋转机构220,EL轴旋转机构230和xEL轴旋转机构240,在操作期间对多个散热器进行方向性控制,廉价地实现了小而轻便且高精度的卫星跟踪性能。 由于在导轨130上不存在驱动部,所以即使与邻接的卫星相连的多波束也不会与驱动部干涉,也可以配置多个散热器。 因此,多波束通过简单稳定的结构实现,并且实现了适于安装在移动台上的布置。 版权所有(C)2005,JPO&NCIPI
