  • Patent number: 11300656
    Abstract: Example embodiments describe a radar sensor, whereby the radar sensor comprises a pair of continuous wave (CW) radar transceivers that each has a leaky wave antenna that are provided adjacent to each other. Each CW radar transceiver comprises a microwave frequency transmission circuit configured to transmit and receive signals reflected off a nearby object. The transmitted and received signals are then processed by the radar sensor to determine a relative displacement between the detected object and the radar sensor. This determined relative displacement may then be used with machine learning techniques to identify dynamic gestures made within the radar sensor's range of detection.

    Abstract: An antenna includes a grounding conductor, a feed conductor, a resonant conductor, and a radioactive conductor. The feed conductor is disposed apart from the grounding conductor. The resonant conductor having a resonant width is disposed along the grounding conductor and disposed apart from the grounding conductor by a resonant-ground distance. The resonant conductor connects to the feed conductor. The radioactive conductor has a radioactive width. One end of the radioactive conductor connects to one end of the resonant conductor with the feed conductor, and another end of the radioactive conductor is disposed apart from the grounding conductor. The radioactive conductor is disposed along the resonant conductor and disposed apart from the resonant conductor by a resonant-radioactive distance. The resonant conductor is positioned between the radioactive conductor and the grounding conductor.

  • Publication number: 20150097751
    Abstract: A planar array antenna structure includes a substrate, an array antenna, and a bottom ground portion. The substrate has a front surface and a rear surface. The array antenna is composed of a plurality of antenna units and disposed on the front surface of the substrate in a symmetrical and polygonal arrangement. A spaced slot is formed between every two antenna units. The bottom ground portion is polygonal and arranged on the rear surface of the substrate. The bottom ground portion has a plurality of included angles thereon, and one notch is formed between two included angles and the notches are correspondingly arranged to the spaced slots. Accordingly, the planar array antenna structure is used to generate high-gain radiation variations, effectively restrain the isolation between the radiators, and significantly increase overall performance of the antenna.

    Abstract: Electronic components, conductors, and the like that the form a detecting-and-transceiving circuit are positioned in a space inside a casing other than a space E that is enclosed by an imaginary surface that forms a predetermined angle ? with respect to a coil axis x toward the outside from a position on the edge of an aperture surface of the end part of a coil-shaped antenna 450 in the direction of the coil axis x. The angle ? is, e.g., 5° or more and is preferably 90°. Minute electronic components and conductors may be positioned within the space E if doing so does not dramatically change the magnetic current of the antenna 450.

    Abstract: The invention provides an antenna for a wireless device, e.g., a cellular phone for wireless mobile telecommunication. The antenna includes a conductive feed strip and a conductive ground component. The ground component is for connecting a ground voltage, and comprises a portion along a surface of the device. The feed strip has a feed port for relaying a feed signal, and does not physically contact the ground component, so as to feed the ground component by noncontact electrical coupling, instead of physical contact.

    Abstract: An on board diagnostic (OBD) device having a radio modem is provided. An antenna of the radio modem is connected to a printed circuit board (PCB) housed within a plastic housing, where the PCB has a ground plane which is extended by a conductive extension. The conductive extension lengthens an effective length of a counterpoise of the antenna without necessitating an increase in size of the OBD device/plastic housing, resulting in maintaining a small form factor for the OBD device, while increasing antenna efficiency and/or bandwidth.
