Dielectric lens apparatus
First Claim
1. A dielectric lens apparatus, comprising:
- a laminate element comprising a plurality of laminate dielectric layers having relative dielectric constants which are different for at least some adjacent layers; and
a dielectric lens element which has a curved surface and which is bonded to a surface of said laminate element with said curved surface facing outwards;
wherein the laminate element and the lens element coact to form a focal point of said dielectric lens apparatus which is positioned within or at said surface of the laminate element.

Abstract
The radiation directivity of radio waves can be controlled more easily over a wider range by using the disclosed dielectric lens. A dielectric lens element having a curved surface is bonded to one of the surfaces of a laminate element in the shape of a flat plate in which a plurality of dielectric layers whose relative dielectric constants are different for adjacent layers are laminated. By controlling the distribution mode of the relative dielectric constants in the laminate element, the radiation directivity for the entire dielectric lens apparatus can be controlled; therefore, the radiation directivity can be controlled more easily over a wider range. A focal point may be positioned within or at the surface of the laminate element, and a signal processing circuit may be formed within and/or at the surface of the laminate element.
