Patent number: 11637379Abstract: In the design of phased array antennas, as well as simple use of compact antennas, there is a strong interest to locate higher frequency antennas closer in spacing, and/or on the same surface, as the larger frequency antennas. What is needed is an array antenna technology, which can be conformal, and can interleave elements, as the frequency increases, to reduce array grating lobes. The desired solution would have much fewer required RF antenna ports, than the Tightly Coupled Dipole Antenna solutions. The optimal solution would also enable Dual or Diverse Polarization. This innovation embeds a wideband Slot Antenna, within the physical area of a larger electric dipole Antenna or Cross Dipole Antenna, with a De-Coupling gap around the Slot Ground Plane (or conductor) and isolates the Wideband Slot Antenna (the inner antenna) from the Dipole or Monopole antenna leg(s) (the Outer Antenna). Both (Inner and Outer) antennas have independent feeds and independent transmission line(s).Type: GrantFiled: October 25, 2019Date of Patent: April 25, 2023Inventor: Mano D. Judd

Patent number: 11626668Abstract: This document describes techniques, apparatuses, and systems directed to a waveguide end array antenna to reduce grating lobes and cross-polarization. Referred to simply as the waveguide, for short, utilizes a core made of a dielectric material to guide electromagnetic energy from a waveguide input to one or more radiating slots. The dielectric core includes a main channel and one or more forks. Each fork connects the main channel to one or more tine sections, and each tine section is terminated by a closed end and a radiating slot. These radiating slots are separated from each other by a distance to enable at least a portion of the electromagnetic energy to dissipate in phase through the radiating slots. The dielectric core of the waveguide reduces grating lobes and cross-polarization associated with the electromagnetic energy. An automobile can rely on the waveguide to detect objects with increased accuracy.Type: GrantFiled: April 19, 2021Date of Patent: April 11, 2023Assignee: Aptiv Technologies LimitedInventor: Mingjian Li

Patent number: 11616306Abstract: This document describes a single-layer air waveguide antenna integrated on a circuit board. The waveguide guides electromagnetic energy through channels filled with air. It is formed from a single layer of material, such as a sheet of metal, metal-coated plastic, or other material with conductive surfaces that is attached to a circuit board. A portion of a surface of the circuit board is configured as a floor of the channels filled with air. This floor is an electrical interface between the circuit board and the channels filled with air. The single layer of material is positioned atop this electrical interface to define walls and a ceiling of the channels filled with air. The single layer of material can be secured to the circuit board in various ways. The cost of integrating an air waveguide antenna on to a circuit board this way may be less expensive than other waveguide-manufacturing techniques.Type: GrantFiled: June 21, 2021Date of Patent: March 28, 2023Assignee: Aptiv Technologies LimitedInventors: Scott D.
