  • Patent number: 11005167
    Abstract: An antenna array consists of multiple sub-arrays of planar, rectangular conductive patches disposed over a cavity to provide a volumetric antenna array. Each sub-array consist of multiple patch elements, arranged typically in a square or rectangular pattern. Multiple sub-arrays are further arranged along a one-dimensional row, to provide one or more unit cells. Adjacent sub-arrays in a row may be oriented at 45 degrees with respect to one another. The assembly provides a wide bandwidth, orientation dependent, directional antenna via volumetric radiating elements that can be conformal to exterior surface(s) of a vehicle such as a roof or trunk or roll bar of a passenger car.

  • Publication number: 20200326607
    Abstract: A scanning Dielectric Travelling Wave Array (DTWA) device suitable for use as a wideband, tunable, two-dimensional beamformer. The device is formed from a set of planar waveguides, elongated waveguide sections and/or progressive delay layers. By controlling the index of refraction (?) of the waveguides, waveguide sections, and/or progressive delay layers, the device to aim at a particular angle of incidence of energy arriving on the top face, in both azimuth and elevation. These indi(cies) of refraction may be controlled with a set of varactors. By observing a constraint on the size of the waveguides as related to the bandwidth of the signals of interest, the waveguide can to receive from or transmit to different directions at the same time. The varactors may be provided by continuous strips of material disposed along the top and bottom of each waveguide section, or as a set of discrete controllable sections distributed along the primary axis of each waveguide section.

  • Publication number: 20190348754
    Abstract: A low profile, conformal antenna assembly provides wide bandwidth, orientation dependent and directional operation via volumetric radiating elements that are diposed over a cavity. The volumetric antenna elements may be further controlled by embedded inductive or capacitive components and/or surrounded by frequency-selective components. An optional AM/FM radiating structure is provided by a conductive wire helix disposed within the cavity. The antenna assembly may be integrated with system and control, conversion, amplification and/or processing electronics in a single enclosure or tightly coupled enclosure space. Integrating the antenna subassembly with an electronics subassembly in the same enclosure eliminates the requirement for discrete RF signal connections reduces associated costs, and avoides signal losses in the connections to multiple vehicle systems. The antenna can be mounted to the inside surface of glass in a vehicle.
