    • The present invention is for providing a production method of a dielectric lens with the excellent productivity, capable of achieving the shape accuracy or density homogeneity of the demanded level, and capable of injection molding of a matching layer without forming a gap with respect to a lens main body. A lens main body is formed by the injection compression molding method, using a composite dielectric material containing a thermoplastic resin as the dielectric material for the lens main body. After forming a matching layer (first surface side matching layer) on either surface of the front or rear surfaces (first surface) side of the lens main body, and injecting a matching layer material, a matching layer (second surface side matching layer) is formed on the other surface of the lens main body (that is, the matching layer is formed by the two operation injection molding method of injecting to one surface side of the lens main body, and then injection to the other surface side).
    • 本发明是为了提供具有优异生产率的电介质透镜的制造方法,其能够实现所需要的水平的形状精度或密度均一性,并且能够相对于透镜形成间隙而能够注射成型匹配层 主体。 通过注射压缩成型方法,使用包含热塑性树脂的复合电介质材料作为透镜主体的电介质材料来形成透镜主体。 在透镜主体的前表面或后表面(第一表面)侧的任一表面上形成匹配层(第一表面侧匹配层)并注入匹配层材料之后,匹配层(第二表面侧匹配层)为 形成在透镜主体的另一个表面上(即,通过注入到透镜主体的一个表面侧,然后向另一个表面侧注入的两种操作注射成型方法形成匹配层)。

    • A dielectric lens which is produced by injection molding of an expandable material consisting of a synthetic resin, a foaming agent and a dielectric constant conditioner. The expandable material is injected into a cavity of a foaming mold up to at least about 80 percent by weight and at least about 100 percent by volume of the capacity of the cavity and is foamed at an expansion ratio of not more than about 1.3. During the foam molding, the surface of the foam-molded body is solidified to be a radome layer. Then, the foam-molded body is transferred from the foaming mold to a shaping mold, in which the foam-molded is cooled down naturally. Further, a fitting tab is provided integrally with the foam-molded body at the edge of the radome layer.
    • 一种介电透镜,其通过注射成型由可合成树脂,发泡剂和介电常数调节剂组成的可膨胀材料制成。 可发泡材料被注入到发泡模具的空腔中,其至少占空间容量的大约80重量%和至少大约100体积%,并以不大于约1.3的发泡比发泡。 在发泡成型过程中,发泡体的表面被固化为天线罩层。 然后,将发泡成型体从发泡模具转移到成形模具中,其中自发地将发泡成型体冷却。 此外,在雷达罩层的边缘处与发泡成型体一体地设置有配合突片。
