摘要:
A system and method of wirelessly communicating in a backplane mesh network is disclosed. A data message received from a first network device is handled at a first antenna system located in a first network device cabinet via a first network interface. The data message is wirelessly transmitted from a first millimeter wave antenna coupled to the first antenna system over a high speed backplane network to a second network device in a second device cabinet using emitted millimeter wave electromagnetic radiation. The data message is wirelessly received at a second millimeter wave antenna over the high speed backplane network using emitted millimeter wave electromagnetic radiation, wherein the received data message is handled by a second antenna system coupled to the second millimeter wave antenna. The received data message is sent, via a second network interface, from the second antenna system to the second network device.

A system and method for encoding and decoding information by use of radio frequency antennas. The system includes one or more interrogator devices and RFID data tags. The RFID data tags include a plurality of antenna elements which are formed on a substrate or directly on an object. The antenna elements are oriented and have dimensions to provide polarization and phase information, whereby this information represents the encoded information on the RFID tag. The interrogator device scans an area and uses radar imaging technology to create an image of a scanned area. The device receives re-radiated RF signals from the antenna elements on the data tags, whereby the data tags are preferably represented on the image. The re-radiated RF signals preferably include polarization and phase information of each antenna element, whereby the information is utilized using radar signal imaging algorithms to decode the information on the RF data tag.

摘要:
A waveguide interface and a method of manufacturing is disclosed. The interface includes a support block that has a printed circuit board. A communication device is coupled to the circuit board. A launch transducer is positioned adjacent to and coupled to the communication device. The launch transducer includes one or more transmission lines in a first portion and at least one antenna element in a second portion. The antenna element radiates millimeter wave frequency signals. An interface plate coupled to the support block has a rectangular slot having predetermined dimensions. A waveguide component is coupled to the interface plate and has a waveguide opening. The first portion of the launch transducer is positioned within the slot such that the slot prevents energy from the transmission line from emitting toward the circuit board or the waveguide opening but allows energy to pass from the antenna element into the waveguide opening.
