Dielectric lens antenna

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.
