MANUFACTURING METHOD OF A DIELECTRIC MATERIAL AND ITS APPLICATIONS TO MILLIMETER-WAVES BEAM FORMING ANTENNA SYSTEMS
摘要
The invention concerns a manufacturing method of a new type of dielectric material having a predefined variable permittivity resulting from the manufacturing process. Main characteristic of the manufacturing method is that in a first step homogeneous dielectric material (100) is shaped in at least a direction and subsequently at least a part thereof is formed so that the resulting dielectric material body (102) has the predefined variation in permittivity in said at least one direction. Said forming step may advantageously comprise sub- steps of deforming at least a part of the shaped dielectric material body and fixing the so deformed dielectric material body. The manufacturing steps are adapted so to induce a predefined variation in permittivity corresponding but not limited to a certain law (e.g. Luneburg, Maxwell,...). The invention further concerns a manufacturing method of an electromagnetic lens that can be used in a millimeter-waves multi-beam forming antenna system where said electromagnetic lens is composed of the new type of dielectric material.
