Focusing device comprising lunegerg lens and method for making such lens

一种聚焦器件，包含有由电介质均匀体构成的棱勃透镜(2、20)，所述电介质均匀体由颗粒大小均匀分布的热塑塑料料粒(6)团组成，其特征是，通过这些料粒的局部熔融利用料粒界面使多个料粒(6)熔接在一起，以便保证所述电介质均匀体被固结在一起。这类透镜特别适用于对非同步卫星进行跟踪，或对至少一个同步卫星进行跟踪，或在MMDS系统中的应用。 The invention relates to a focusing device comprising a Luneberg lens comprising a homogeneous volume of dielectric. It is characteriz...

Zusammenfassung:	一种聚焦器件，包含有由电介质均匀体构成的棱勃透镜(2、20)，所述电介质均匀体由颗粒大小均匀分布的热塑塑料料粒(6)团组成，其特征是，通过这些料粒的局部熔融利用料粒界面使多个料粒(6)熔接在一起，以便保证所述电介质均匀体被固结在一起。这类透镜特别适用于对非同步卫星进行跟踪，或对至少一个同步卫星进行跟踪，或在MMDS系统中的应用。 The invention relates to a focusing device comprising a Luneberg lens comprising a homogeneous volume of dielectric. It is characterized in that the dielectric comprises a granular agglomerate defined by a homogeneous granule size distribution of thermoplastic granules, at least one plurality of these granules being welded together by granule boundaries in order to keep said volume consolidated. Particular application to lenses for the tracking of nongeostationary satellites, of at least one geostationary satellite, or for use in an MMDS system.
