Lens antenna

A method and an apparatus for producing an adhesive tape are disclosed in which an adhesive tape is produced while a liquid reservoir is almost hermetically sealed by bringing a blade into contact with an upper laminate roller, and supplement of adhesive to the liquid reservoir is controlled so that the liquid surface of the adhesive reserved in the liquid reservoir comes into contact with the back face of the blade.

Method and apparatus for producing adhesive tape, and adhesive tape

A compact lens antenna assembly A which is a Luneberg lens antenna comprising a hemispherical lens and a reflecting plate so as to converge incoming radio waves on a feed, and which can receive radio waves from not only a geostationary satellite or an orbiting satellite with high gain even if the incidence angle of the incoming radio waves is large includes lens antenna bodyincluding a base plate, a reflecting plateand a hemispherical lensmade by laminating dielectric materials. The plateand the lensare rotatably mounted on the base plate. The antenna body further includes feedsandthat can be moved to a desired position along guide rails. The antenna assembly further includes a reflecting plate support meansmounted on a baseand capable of inclining the reflecting platein a desired direction. By inclining the reflecting plate, the incidence angle of radio waves from the satellite is adjustable to a value within a predetermined range.

It is an object of the present invention to provide a dielectric resin foam which has high and uniform dielectric properties and is preferable for use as various dielectric materials. A dielectric resin foam obtained by expanding a resin composition comprising a synthetic resin and a fibrous and/or plate-like dielectric inorganic filler is provided.

Dielectric resin foam and lens for radio waves using the same

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.
