  • Patent number: 11936415
    Abstract: 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.

  • Patent number: 6957979
    Abstract: The present invention is a pawl latch which is adapted to be mounted to a first member, such as a closure panel of drawer face plate for releasably retaining the closure panel against an enclosure. Such drawer is suitable for implementing an electronic module which plugs into the backplane of the enclosure. The latch has spring-assisted engagement and disengagement of its pawl with the edge of an enclosure opening against which the pawl operates. This results in spring-assisted inject and eject functions for connecting and disconnecting any associate backplane connection. The latch is low profile with a narrow footprint and has an EMI and ESD event preventive coating on the surface of the housing and appropriate components thereof. A pull handle is substantially flush with the outside face of the latch housing and cooperates with a button spring activator member, when the handle is in the closed position.
