    摘要: A portable device, such as a handheld device (10), laptop device or other suitable portable device, employs an antenna beam selection structure that is coupled to a plurality of built-in antennas (12 and 14) of the portable device that have different beam angles with respect to each other. The plurality of built-in antennas are coupled to a satellite network positioning signal processing circuit (18) so that device positioning signals from a satellite network can be received and processed by the device. The plurality of built in antennas may be stationary or movable with respect to each other. A control circuit (20) is operative to control switching between each of the plurality of built in antennas based on detected signal strength, signal quality measurements, the number of positioning satellites detected by a satellite network positioning signal processing circuit or other suitable criteria.

    摘要: An antenna (100) is provided, which can be used in a wireless communication device or a base transceiver station forming part of the infrastructure of a wireless communication system. The antenna includes a first plate conductor (102) and a second plate conductor (104), which are substantially symmetric. The first plate conductor and the second plate conductor are separated by a central slot (106) and include respective primary feed points proximate the central slot, which are adapted for receiving a differential signal from a differential signal source (108). The first plate conductor and the second plate conductor exhibit at least a first frequency response (F1) and a second frequency response (F2) dependent on various dimensions of both the first plate conductor and the second plate conductor, relative to their respective primary feed point.

    摘要: A wireless communication device for minimizing electromagnetic interference with hearing aid devices. The wireless communication device comprises a lower housing (112, 312, 412, 512, 612) and an upper housing (114, 314, 414, 514, 514) adjacent to the lower housing. The lower housing (112, 312, 412, 512, 612) supports a wireless transceiver (108, 202) capable of producing an electromagnetic field, and the upper housing includes an ear piece (104, 504, 604). For one embodiment the upper housing (114, 314, 514, 614) and all components supported by the upper housing consist of non-electromagnetic conductive material. For other embodiments, all electromagnetic conductive components of the upper housing (414, 514, 614) are restricted to an area adjacent to an ear piece (104, 504, 604) of the upper housing.

    摘要: An internal antenna system (200) for reducing interference in a wireless communication device (100) is provided. The internal antenna system (200) comprises an antenna (202) and a housing (110). The housing is configured to reduce interference in the transmission caused by the metal surface of the housing. The housing is made of or plated with an electromagnetically transparent decorative metal (ETDM). The housing has metal islands, which are separated from each other by gaps. These gaps in the ETDM surface allow the radio frequency (RF) energy of signals transmitted by the antenna to pass through.
