Abstract:
1. An antenna element, comprising: a ground plane defining a volume; a feed, wherein said feed includes a proximate end and a distal end; a first dielectric material, wherein the first dielectric material is included in the volume defined by the ground plane, and wherein at least a portion of the first dielectric material is located between the feed and the ground plane; and a second dielectric material, wherein at least a portion of the second dielectric material is also included in the volume defined by the ground plane, wherein the first dielectric material and the second dielectric material, taken together with one another, fill substantially all of the volume defined by the ground plane, wherein the first dielectric material has a first dielectric constant, wherein the second dielectric material has a second dielectric constant, wherein the first and second dielectric constants are different from one another, and wherein the first and second dielectric materials form at least part of a lens perturbation feature.
