Patent number: 7107016Abstract: A structural arrangement for a wireless communication terminal includes a case in which are disposed a sound transducer and a patch planar antenna connected to a printed circuit. The transducer has an electrically neutral portion comprising a vibrating membrane and an electrically conductive portion. The antenna incorporates a cavity delimited by a ground plane and a conductive patch disposed on a dielectric support. The electrically neutral portion of the sound transducer is situated in the cavity of the antenna. The electrically conductive portion of the sound transducer constitutes a portion of the ground plane of the antenna.Type: GrantFiled: September 12, 2002Date of Patent: September 12, 2006Assignee: TCL Communications Technology Holdings LimitedInventors: Stéphane Dufosse, Pascal Herve, José Marie Baro, Bertrand Cupif

Patent number: 6642891Abstract: A transceiver, which may be a telephone for mobile networks, includes a metal or screened casing, an antenna support mounted on the casing at one end of the antenna support, and an antenna mounted on the other end of the antenna support. The antenna support has a physical or electrical length substantially equal to one quarter of the wavelength of waves emitted by the antenna. The transceiver has improved link efficiency.Type: GrantFiled: February 7, 2000Date of Patent: November 4, 2003Assignee: AlcatelInventor: José Marie Baro
