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. COPYRIGHT: (C)2005,JPO&NCIPI
