RADIO WAVE LENS ANTENNA APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a radio wave lens antenna apparatus capable of readily adjusting a plurality of antenna elements in position towards a plurality of stationary satellites. SOLUTION: The radio wave lens antenna apparatus has a structure wherein the antenna apparatus having a hemispherical Luneberg lens 2 mounted on a reflecting plate 1 is provided with a support arm 4 that strides over the lens 2. A circular arc element holding section 4a along the spherical face of the lens 2 of the support arm 4 accompanied by an elevation angle adjuster 5 for adjusting an elevation angle, is provided with an antenna element 3 by way of a mounting means 6 at a gap corresponding to the gap of a stationary satellite to position a plurality of antenna elements in a batch by rotating the support arm 4 to a predetermined angle position. The structure includes a cover and the like, having a pointing map drawn thereon, which serves as an index for positioning the antenna elements enabling the setting points of the antenna elements to be checked through the map.
