    Abstract: A dielectric element includes a bottom surface, a top surface, and a plurality of cells formed vertically between the bottom surface and the top surface. Each cell of the plurality of cells includes a cell sidewall that extends below the top surface toward the bottom surface. The cell sidewall forms an aperture in the top surface and tapers from the top surface toward a center of a respective cell. Each cell sidewall is formed of a dielectric material.

    Abstract: A dielectric lens is disclosed comprising a center portion that extends along a cylinder having a central axis and a plurality of spoke portions that are attached to the center portion and extend to a spherical perimeter region in a radial direction from the center portion. The plurality of spoke portions includes at least a first monolithic spoke portion extending from the center portion to the spherical perimeter region and the center portion and the plurality of spoke portions define a plurality of cavity regions among the plurality of spoke portions. The center portion, the cylinder, the plurality of spoke portions, and the plurality of cavity regions are included in a gradient index (GRIN) dielectric lens having a plurality of relative permittivities that are based on a radial distance from the center portion.

    Abstract: A radio frequency (RF) antenna including a patch antenna element, a microstrip transmission line, a ground plane, a waveguide, and a dielectric lens. The patch antenna element is disposed on a top surface of a first substrate of the RF antenna, and includes a slot aperture through which the patch antenna element is configured to be electromagnetically coupled to the microstrip transmission line. The microstrip transmission line is disposed between the first substrate and a second substrate. The ground plane is disposed on a third substrate. The microstrip transmission line is configured to be electromagnetically coupled to the ground plane. The waveguide includes a proximal aperture attached to the top surface and enclosing the patch antenna element. The waveguide includes a distal aperture opposite the proximal aperture, and the waveguide is configured to be electromagnetically coupled to the patch antenna element. The dielectric lens is disposed in the distal aperture.
