  • Publication number: 20230288532
    Abstract: An antenna assembly includes first and second feed antennas and a lens element. The first feed antenna is arranged to transmit outbound radio waves of a transmitter beam. The second feed antenna is arranged to capture a received RF signal. The lens element is arranged to collimate the transmitter beam and to focus the receiver beam. The first and second feed antennas are disposed on a conductive ground plane that is offset from a back end of the lens element by a predefined distance in direction of a center axis of the lens element. A volume between the back end of the lens element and the ground plane comprises material that has a refractive index that is smaller than that of the lens element for converging the outbound and inbound RF beams between the back end of the lens element and the first and second feed antennas.

  • Patent number: 6952200
    Abstract: A mobile communication device has a body portion (2) and a lid (7) hingeably coupled to the body portion (2). The lid (7) is moveable about a hinged joint (8) between open and closed positions in which a surface portion of the body portion (2) is respectively uncovered and covered by the lid. A first plurality of data input keys (11b) are provided on said surface portion of the body portion (2) whilst a second plurality of data input keys (11a) are provided on an inner surface of the lid (7). The first and second plurality of keys combine, when the lid (7) is open, to provide a QWERTY keyboard. A third plurality of keys (10) on an outer surface of the lid (7) provide a set of telephone keys for use when the lid (7) is closed. An electronic display (6) is provided on a surface of the body portion (2), the display (6) being visible to a user when the lid (7) is in both the open and closed positions.
