  • Patent number: 10931031
    Abstract: A GNSS compact antenna comprising a conducting ground plane and a driven element for exciting right hand circularly polarized waves having a multi-segment structure such that the area around the driven element is divided into elementary cells with conductors and circuit elements arranged therein. The antenna includes a set of circuit elements connecting the neighboring elementary cells and the driven element. Each elementary cell has a horizontal conductor over the ground plane, and each elementary cell can have a vertical conductor and a circuit element connecting the horizontal and vertical conductors. The horizontal conductor comprises a set of characteristic points to which circuit elements, connecting neighboring elementary cells or any elementary cell and the driven element, are connected. Both the impedance of each circuit elements and the design of each elementary cell can be different, but the antenna has four-fold rotational symmetry relative to the vertical axis.

  • Patent number: 10197679
    Abstract: An antenna system includes an electromagnetic radiator assembled on a ground plane. The ground plane containing a nontransparent area in a center of the ground plane and a semitransparent area surrounding the nontransparent area. The nontransparent area is circular in shape. The semitransparent area is generally circular in shape and contains at least one slot. A plurality of vertical conducting elements are in proximity of a boundary between the nontransparent area and the semitransparent area on a bottom side of the ground plane. The vertical conducting elements are arranged in a circle around a center of the electromagnetic radiator.

  • Patent number: 10170823
    Abstract: An antenna assembly includes a GNSS stacked patch antenna located in a metal cavity and a matching parasitic element, the matching parasitic element includes a set of conductors not connected to the antenna. Each conductor has an external end and internal end, the external ends being conductively coupled to the housing of the cavity. The conductors of the matching parasitic elements can be radially arranged. External ends of conductors are additionally connected to each other by a ring-shaped conductor. Internal ends of conductors can be connected to capacitive elements, which can be discrete capacitors and/or segments of conductors.

  • Patent number: 9520651
    Abstract: Disclosed is a dual-band Global Navigation Satellite System antenna with a hollow core. The antenna includes a conductive cylindrical tube with a longitudinal axis. A ground plane, a low-frequency radiator, and a high-frequency radiator are annuli orthogonal to the longitudinal axis. The inner peripheries of the ground plane and the low-frequency radiator are electrically connected to the outer surface of the cylindrical tube. The outer periphery of the high-frequency radiator is electrically connected to the low-frequency radiator. A vertical low-frequency radiating gap is configured between the ground plane and the outer periphery of the low-frequency radiator. A horizontal high-frequency radiating gap is configured between the inner periphery of the high-frequency radiator and the outer surface of the cylindrical tube. In an embodiment, the inner diameter of the cylindrical tube has a value from about 27 mm to about 102 mm, permitting insertion of a post or pole.
