  • Publication number: 20250070482
    Abstract: A waveguide antenna system, includes: an electromagnetic, EM, transition portion having a transition region having a signal feed interface and an open waveguide section, the EM transition portion configured to couple EM energy from the signal feed interface to a guided waveguide mode of EM energy to the open waveguide section via the transition region; and a leaky waveguide antenna portion configured and disposed to radiate electromagnetic energy received from the open waveguide section; wherein the EM transition portion is electromagnetically coupled to the leaky waveguide antenna portion, the EM transition portion being configured to support a transfer of electromagnetic energy from a signal feed structure to the leaky waveguide antenna portion.

  • Publication number: 20240396223
    Abstract: An combination of an open trough waveguide antenna (TWGA) and lens fixedly attached to the TWGA. The combination of the TWGA and lens provides an antenna assembly that is suitable for use in a radio frequency antenna applications. The lens has a dielectric medium, and a plurality of non-conductive filler particles dispersed in the dielectric medium. The lens has a relative dielectric constant (Dk) of equal to or less than 2; the lens has a thickness, T, of equal to or greater than 5 microns, and equal to or less than 500 microns.

  • Patent number: 10619680
    Abstract: A clutch thrust bearing device having a ball bearing with a fixed inner ring, a rotatable outer ring, and at least one series of balls located in a raceway chamber disposed between the rings. The device also provides a piston having a substantially radial portion, the fixed inner ring being in axial abutment against the substantially radial portion. The piston further provides an axial portion arranged in a bore of the fixed inner ring of the ball bearing, the axial portion being provided with at least one outwards radial projection that extends between the fixed inner ring and the rotatable outer ring.
