<p>An antenna system (50) of the invention includes a plurality of antenna devices (26) respectively configured to send or receive a plurality of radio beams, a plurality of electric feeding units (20,23) respectively holding the plurality of antenna devices (26) and a spherical lens (1) having a center (O) and causing the plurality of radio beams to converge into the plurality of antenna devices (26) respectively. A holding rail (12) holds the plurality of electric feeding units (20,23) in such a manner that the plurality of antenna devices (26) are movable along a substantially constant distance from the center of the spherical lens. According to the antenna system (50), the plurality of electric feeding units (20,23) can be arranged for one spherical lens (1) to follow the plurality of satellites (41,42). Thus, the antenna system (50) can be arranged in a smaller space.</p> |
