Abstract
Official abstract text for this publication.
A Luneburg antenna device includes a dielectric lens and an array antenna. The dielectric lens is a laminate of a plurality of disc members having distribution of permittivity varying with respect to its radial direction. Each of the disc members includes a planar section in which a thickness dimension of a radially outer area is smaller than a thickness dimension of a radially inner area and a fin section which extends in a radial manner from a central portion of the planar section toward a radially outer side and in which a radially inner area and a radially outer area have the same thickness dimension.
First claim
Opening claim text (preview).
The invention claimed is: 1. A dielectric lens comprising: a laminate of a plurality of disc members, each of the disc members having distribution of permittivity varying with respect to a radial direction thereof, wherein the disc member includes a planar section in which a thickness dimension of a radially outer area is smaller than a thickness dimension of a radially inner area and a fin section which extends in a radial manner from a central portion of the planar section toward a radially outer side and in which a radially inner area has a same thickness dimension with a radially outer area. 2. The dielectric lens according to claim 1 , wherein the fin section includes a plurality of depressions positioned between its center and outer edge in the radial direction and a plurality of projections positioned other than the depressions, thickness dimensions of the depressions are smaller than thickness dimensions of the projections, a length dimension of each of the depressions in the radial direction is set at a value smaller than ¼ of a wavelength of a radio wave to be used, and a length dimension of each of the projections in the radial direction is set at a value smaller than ¼ of the wavelength of the radio wave to be used. 3. The dielectric lens according to claim 1 , wherein the plurality of disc members have a same outer diameter dimension, and the laminate of the disc members has a cylindrical shape.
