  • Publication number: 20210218134
    Abstract: The embodiment of the present disclosure provides an antenna structure and an antenna array. The antenna structure comprises a first antenna component which comprises: a first three-dimensional antenna with one end grounded or connected with a reference potential; a single antenna port connected with the other end of the first three-dimensional antenna; and a first parasitic structure provided adjacent to the first three-dimensional antenna. In the antenna structure, the first three-dimensional antenna is only connected with a single antenna port, so that the number of ports required by the antenna can be reduced, that is, the power consumption can be reduced from the antenna dimension, thereby simultaneously reducing heat generation and maintaining stable overall wireless performance.

  • Patent number: 9653777
    Abstract: An electronic device may have a metal housing. The metal housing may have an upper housing in which a component such as a display is mounted and a lower housing in which a component such as a keyboard is mounted. Hinges may be used to mount the upper housing to the lower housing for rotation about a rotational axis. A slot-shaped opening may separate the upper and lower housing. A flexible printed circuit with ground traces may bisect the slot-shaped opening to form first and second slots. Cavity antennas may be aligned with the slots. Each cavity antenna may include a hollow carrier with a pair of speakers. The speakers may have ports that emit sound through aligned openings in the lower housing. Conductive gaskets surrounding the ports may acoustically seal the speaker ports while shorting the cavity antenna to the lower housing.
