Radome-lens EHF antenna development |
摘要 |
A radome-lens comprises a shell of dielectric material having an outer surface in the form of a small circle defined by a sphere and a plane intersecting the sphere, an opening at one end of the shell for reception of an antenna therein, the surface having a central axis which is normal to the plane and extends through the center of the sphere, and an inner surface having a spherical portion centered at a second center disposed along the axis adjacent the first mentioned center but spaced toward the outer surface. When so constructed, the invention functions as a radome in the sense that it houses and protects an antenna in the usual manner and also functions as a lens in the sense that it amplifies the scan angle of the antenna from an angle of less than 90 DEG to 90 DEG or more.
