Patent number: 11942688Abstract: A radio frequency (RF) aperture includes an array of electrically conductive tapered projections arranged to define a curved aperture surface, such as a semi-cylinder aperture surface, or a cylinder aperture surface (which may be constructed as two semi-circular aperture surfaces mutually arranged to define the cylinder aperture surface). The RF aperture may further include a top array of electrically conductive tapered projections arranged to define a top aperture surface. The top aperture surface may be planar, and a cylinder axis of cylinder aperture surface may be perpendicular to the plane of the planar top aperture surface. The RF aperture may further include baluns mounted on at least one printed circuit board, each having a balanced port electrically connected with two neighboring electrically conductive tapered projections of the array and further having an unbalanced port.Type: GrantFiled: February 3, 2023Date of Patent: March 26, 2024Assignee: BATTELLE MEMORIAL INSTITUTEInventors: Raphael Joseph Welsh, Douglas A. Thornton

Patent number: 11936415Abstract: An air interface plane (AIP) of a radio frequency (RF) aperture includes: a circuit board having a first side and a second side opposite the first side; and a matrix of tapered elements arranged on the first side of the circuit board and secured to the circuit board, the matrix of tapered elements cooperating to at least one of receive or transmit an over-the-air RF signal. Suitably, each tapered element of the matrix has: a central hub extending along a longitudinal axis from a hub base which is proximate to the first side of the circuit board to an apex of the tapered element which is distal from the first side of the first circuit board; and a plurality of arms extending from the central hub at the apex of the tapered element, each of the plurality of arms including a first portion that projects the arm radially away from the longitudinal axis and a second portion that projects the arm longitudinally toward the first side of the circuit board.Type: GrantFiled: April 26, 2023Date of Patent: March 19, 2024Assignee: BATTELLE MEMORIAL INSTITUTEInventors: Raphael Joseph Welsh, Douglas A.

Publication number: 20230208550Abstract: A radio frequency (RF) jamming device includes a differential segmented aperture (DSA), a jammer source outputting a jamming signal at one or more frequencies or frequency bands to be jammed, and RF electronics that amplify and feed the jamming signal to the DSA so as to emit a jamming beam. The DSA includes an array of electrically conductive tapered projections, and the RF electronics comprise power splitters configured to split the jamming signal to aperture pixels of the DSA. The aperture pixels comprise pairs of electrically conductive tapered projections of the array of electrically conductive tapered projections. The RF electronics further comprise pixel power amplifiers, each connected to amplify the jamming signal fed to a single corresponding aperture pixel of the DSA. The RF jamming device may include a rifle-shaped housing, with the DSA mounted at a distal end of the barrel of the rifle-shaped housing.Type: ApplicationFiled: March 7, 2023Publication date: June 29, 2023Inventor: Raphael Joseph Welsh
