Abstract:

An RF antenna grid design in which the antenna array is installed on a patch panel cover allows for the retrofitting of an RF antenna grid on existing patch panel based systems without disrupting network operation. An apparatus for determining connectivity between device ports on a patch panel and cable ends having corresponding RFID tags attached thereto comprises a patch panel having a plurality of device ports and a patch panel cover comprising a plurality of RFID antennas, where each of the RFID antennas comprises one or more protruding portions thereof, each of the protruding portions of the RFID antennas being in close physical proximity to one or more of the plurality of device ports when the patch panel cover is positioned in a fixed positional relationship to the patch panel (e. g. , when the patch panel cover is “attached” to the patch panel).

Abstract:

The present invention relates to an antenna array for supporting multiple beam architectures. For example, a transceiver may include an antenna array. The antenna array includes a plurality of antenna elements, where the plurality of antenna elements is configured to support at least two beam architectures in a cell site. Each beam architecture is associated with a different configuration of sectors and beamforming signals. According to one embodiment, each beam architecture is associated with a different wireless standard. According to another embodiment, each beam architecture is associated with a different carrier within one wireless standard. The antenna elements may be arranged as a circular array.

Assignee:

AT&T Corp. - Murray Hill NJ

International Classification:

H01Q 138

US Classification:

343700MS

Abstract:

A diode detector is integrated into a microstrip patch antenna. Tuning and matching of the detector are accomplished by adjusting the geometry of the patch. Cost, power consumption, losses, and spurious responses are reduced. The antenna may be adapted to a mixer, video detector, i. f. detector, or audio detector.

Assignee:

Lucent Technologies - Murray Hill NJ

International Classification:

H01L 2166

US Classification:

437 8

Abstract:

The disclosed method of making a semiconductor device comprises a screening procedure that facilitates identification of devices having relatively low flicker noise. The devices are typically semiconductor diodes. The procedure utilizes our discovery of a correlation between the reverse bias current I. sub. r of a semiconductor device and the flicker noise power, and comprises measurement of the reverse bias current and comparison of the measured value with a predetermined comparison value I. sub. rc. Devices having I. sub. r. ltoreq. I. sub. rc are those that have relatively low flicker noise. The screening procedure is simple and quick, and can be readily performed in a manufacturing environment.

Abstract:

A miniature, multi-branch patch antenna suitable for operating in the 1 GHz to 100 GHz frequency range, a method for making same and a communication system using the same is disclosed. In one embodiment, the antenna comprises a planar dielectric substrate, a plurality of conducting antenna elements each having a feed port, a ground plane and a septum located between each conducting antenna element. In a second embodiment, the antenna comprises a planar dielectric substrate, a plurality of conducting antenna elements each having a feed port, a ground plane and a superstrate that is disposed on the plurality of conducting antenna elements and at least a portion of the dielectric substrate. The septum and the superstrate suppress undesirable coupling mechanisms. In a communication system according to the present invention, the miniature, multi-branch patch antenna is coupled to a transmitter and/or receiver.
