Abstract
A small, lightweight radio wave lens antenna device is proposed in which freedom of selection of the installation place is high, which can be compactly installed e.g. on a wall surface, and in which restriction of installation space is relaxed. A hemispherical Luneberg lensis mounted on a reflecting plate, antenna elementsare supported by a retainer, they are integrally combined, and a mounting portionis provided for mounting the reflecting plateto a installation portion such as a wall surface with the reflecting platesubstantially vertical. The reflecting platemay have such a shape that an area other than the area for reflecting radio waves from directions in a predetermined range is removed, preferably in the shape of a fan. The hemispherical Luneberg lensis mounted on the reflecting plate, offset toward the small arcuate edgeof the fan. Further, a support armstraddling the lensis provided in the antenna device having a hemispherical Luneberg lensprovided on the reflecting plate, antenna elementsare mounted on an arcuate element retaining portionof the support armalong the spherical surface of the lenswith an angle adjustorfor adjusting the elevation at intervals corresponding to the distances between geostationary satellites by means of mounting means. Thereafter, the support armis pivoted to a predetermined angular position so that the antenna elements can be comprehensively positioned.
