  • Patent number: 10431904
    Abstract: An antenna array assembly comprises a dielectric film (2) carrying an array of conductive patch radiator elements (7) and a plurality of conductive feed tracks and a ground plate (1), a face of the ground plate (1) having a contoured shape comprising a first part configured to be in contact with the dielectric film (2), and a second part comprising sunken sections with respect to the first part arranged to underlie the conductive feed tracks and conductive patch radiator elements (7), and the ground plate having locating protrusions (6g, 6f) protruding from the first part. The dielectric film is attached to the ground plate by location of holes in the dielectric film with the locating protrusions (6g, 6f) such that the dielectric film is held under tension to maintain spacing of the dielectric film (2) from the sunken sections of the ground plate (1) without the use of a dielectric spacer layer between the dielectric film (2) and the ground plate (1).

  • Publication number: 20190190110
    Abstract: A radio frequency transmission arrangement comprises a ground plate having an aperture comprising a slot with an elongate cross-section and substantially parallel sides, and a first and second transmission line. The thickness of the ground plate is greater than a width of the slot. The aperture is partially filled with a solid dielectric material and partially filled with air. The first transmission line comprises a first elongate conductor on a first side of the ground plate and has an end terminated with a first termination stub. The second transmission line comprises a second elongate conductor on the opposite side of the ground plate and has an end terminated with a second termination stub. The first transmission line is arranged to cross the slot at a point adjacent to the first termination stub, and the second transmission line is arranged to cross the slot at a point adjacent to the second termination stub.

  • Patent number: 10211525
    Abstract: An antenna array assembly comprises at least a first and second antenna element, each comprising at least one radiator element in a substantially parallel relationship to a respective ground plate, and an isolator bar disposed between the respective ground plates of the first and second antenna elements, the isolator bar being elongate having a cross-section comprising a T shape, the cross-section being across a long axis. The isolator bar comprises a support bar in contact with the ground plates forming the stem of the T shape, and a cross piece forming the top of the T shape. The cross piece of the isolator bar has a width in the cross-section of at least a quarter of a wavelength at an operating frequency of the antenna array, whereby to provide radio frequency isolation between the first and second antenna elements.

  • Patent number: 9000971
    Abstract: Potential radar pulses are detected in a received signal waveform at a terminal of a broadband radio communication system, and a reception time is ascertained for each of the potential radar pulses. A pair of pulses is selected having respective reception times separated by an allowed pulse repetition intervals. One or more further pulses is selected that is related to the selected pair by having a respective reception time separated from the respective reception time of at least one pulse of the pair of pulses by one or more pulse repetition intervals from the set of pulse repetition intervals.
