  • Patent number: 10454223
    Abstract: The present application describes a connector assembly, a circuit board assembly, a cable assembly and to a method of manufacturing a connector assembly. A connector assembly comprises a shroud; and a plurality of co-axial radio frequency connectors at least partially received in the shroud such that the shroud extends around each radio frequency connector and between adjacent radio frequency connectors. The shroud comprises at least one piece of radiowave absorption material arranged to absorb radio frequency energy leaking or dispersing from the radio frequency connectors in use. Another connector assembly comprises a body, a plurality of radio frequency connectors at least partially received in the body, and a conductive foil integrally formed with the body and partially extending beyond the body.

  • Patent number: 8462519
    Abstract: There is disclosed a method of shielding a circuit board, a circuit board, an electromagnetic shield and a method of manufacturing an electromagnetic shield. In an aspect, the method comprises placing a first electromagnetic shield over a first area of the circuit board and placing a second electromagnetic shield over a second area of the circuit board. At least one of the electromagnetic shields has at least one projection therefrom that contacts and makes electrical connection with a surface of the other electromagnetic shield when the shields are placed on the circuit board.

  • Patent number: 7327323
    Abstract: Communications apparatus has a plurality of nodes each of which is capable of communicating with plural other nodes via point-to-point wireless transmission links between the nodes. At least one of the nodes has at least one antenna that is steerable in azimuth. The antenna is arranged to transmit an electromagnetic beam that has a beam width that is narrower in azimuth than in elevation. The beam width in azimuth is less than 9° and the beam width in elevation is less than about 15°.

  • Patent number: 7280011
    Abstract: A hollow waveguide (1) has a wall (3) having plural pegs (16) thereon. The pegs (16) which project into the hollow interior of the waveguide (1) such that the waveguide (1) propagates electromagnetic waves only below a certain frequency. The surface of each of the pegs (16) is substantially free of discontinuity and concavities. The waveguide (1) may be manufactured by a moulding process.

  • Publication number: 20050061528
    Abstract: A shielding device (102) is provided for a circuit board that has components thereon which operate at 10 GHz or above. The shielding device (102) has a face with a plurality of component recesses (104-109) therein each for receiving a portion of at least one component. At least some of the shielding device (102) is formed of a material that is absorptive of electromagnetic radiation having a frequency of about 10 GHz or above. The electrical properties of the material and the dimensions of the component recesses (104-109) are arranged such that, when the shielding device (102) is used in conjunction with a circuit board, the shielding device (102) suppresses undesired propagation of electromagnetic radiation between components of the circuit board.
