    摘要: The antenna element mounting of the present invention enables an antenna to be mounted between the printed circuit boards of a radio instead of along side the boards. The shielding of the printed circuit boards has an indentation along one edge of each shield. When the shields are mated, the indentations form a channel into which the antenna is mounted.

    摘要: An antenna system for a communication device. A whip antenna is surrounded by a helical antenna. A switch couples the helical antenna to the signal source when the whip antenna is in a retracted position. The whip antenna is comprised of an upper conductive portion, a lower conductive portion, and a dielectric portion which isolates the upper and lower conductive portions from each other. A conductive sleeve member surrounds the whip antenna and is slidably mounted thereon. In a first embodiment, when the whip antenna is extended, the conductive sleeve member slides over the dielectric portion, coupling the upper and lower conductive portions together. As the whip antenna is retracted, the helical antenna pushes the conductive sleeve member to the top end of the whip antenna, isolating the whip antenna from the helical antenna. In a second embodiment, the helical antenna is an integral part of the conductive sleeve member.

    摘要: A selectively coupled two-piece antenna for use in a mobile phone having a casing and radio frequency (RF) communications circuitry includes a composite radiator that is selectively extendable from and retractable into the casing and a communications interface that is connected to the RF communications circuitry. The composite radiator has first and second radiating elements, and a connecting element. When the composite radiator is extended, the connecting element connects the first and second radiating elements. In this position, the communications interface connects the RF communications circuitry to the first and second radiating elements. Thus, the RF communications circuitry transmits and/or receives RF signals through both the first and second radiating elements as a top loaded antenna. However, when the composite radiator is retracted, the connecting element electrically isolates the first and second radiating elements.

    摘要: A testing chamber is configured to evaluate the accuracy of a wireless communication device under test in a production environment. The configuration of the testing chamber may resemble an enclosed structure having a wall that includes multiple layers. An array of antennas, which serves as a layer of the wall, is strategically positioned within the testing chamber to receive and transmit signals emitted to/from the wireless communication device. Located within the testing chamber is either a stationary or moveable holder to support the wireless communication device. Furthermore, during testing, the forward link and the reverse communication links are monitored by selectively or alternatively adjusting and shifting the phase/amplitude of the antenna of the wireless communication device to mitigate the effects of multi-path fading.

    摘要: An antenna interface for a wireless communication device is provided which comprises an outer grounded shell and an inner signal shell, separated by an intermediate dielectric shell. Preferably, the interior surface of the inner signal shell is threaded to accept either an antenna securement member, or a test equipment interface connector. With this interface, an antenna can be driven by the inner signal shell, and two-conductor test equipment can be coupled to the wireless communication device via both the inner signal shell and the outer grounded shell.
