  • Publication number: 20190020122
    Abstract: A radio-frequency responsive device includes a dielectric substrate having a first side and an opposite second side. A Van Atta array reflector is printed on the first side of the dielectric substrate. The Van Atta array reflector reflects an incident signal at a predetermined radio frequency at an incident angle. A conductive ground layer is disposed adjacent the second side of the dielectric substrate. In a method of making a radio-frequency responsive device, a Van Atta array reflector is printed on a first side of a dielectric substrate. A conductive ground layer is applied to a second side of the dielectric substrate, in which the second side is opposite the first side.

  • Patent number: 9214722
    Abstract: An antenna includes a dielectric sheet and a conductive film. The dielectric sheet is folded into a plurality of fold segments and is configured to be compressed into a compressed state and to be expanded into an expanded state. The conductive film is disposed on a portion of the dielectric sheet. The conductive film has a pattern that defines a current path from the bottom of the dielectric sheet to the top of the dielectric sheet. The pattern is configured so that the each of the plurality of fold segments includes a portion of the pattern and so that the portion of the pattern on each fold segment is substantially non-juxtaposed with respect to the portion of the pattern on each adjacent fold segment when the dielectric sheet is fully compressed into the compressed state.

  • Patent number: 7196666
    Abstract: A surface micromachined electromagnetically radiating antenna includes a coplanar waveguide on a ground plane coated substrate having a conductor path. The conductor path is coupled to a monopole conductor, which has a generally-cylindrical backbone erected vertically from the substrate and a metal layer deposited on the backbone at a predetermined thickness. The antenna may be fabricated by depositing an epoxy on the ground plane coated substrate to a predetermined depth and according to a pattern. The epoxy is exposed to an ultraviolet source that develops one or more columns according to the pattern. A seed layer of metal may be formed on the developed column. A conductive metal is electrodeposited over the column surface to produce the monopole antenna. Other antenna may be created by adding monopoles and/or conductive metal patches and/or strips that are positioned atop the monopoles and elevated from the substrate.

  • Publication number: 20060291598
    Abstract: A wireless communication system can comprise two or more antennas that interfere with one another via free space coupling, surface wave crosstalk, dielectric leakage, or other interference effect. The interference effect can produce an interference signal on one of the antennas. A cancellation device can suppress antenna interference by generating an estimate of the interference signal and subtracting the estimate from the interference signal. The cancellation device can generate the estimate based on sampling signals on an antenna that generates the interference or on an antenna that receives the interference. The cancellation device can comprise a model of the crosstalk effect. Transmitting test signals on the communication system can define or refine the model.

  • Publication number: 20060178157
    Abstract: Signals propagating on an aggressor communication channel can cause interference in a victim communication channel. A sensor coupled to the aggressor channel can obtain a sample of the aggressor signal. The sensor can be integrated with or embedded in a system, such as a flex circuit or a circuit board, that comprises the aggressor channel. The sensor can comprise a dedicated conductor or circuit trace that is near an aggressor conductor, a victim conductor, or an EM field associated with the interference. An interference compensation circuit can receive the sample from the sensor. The interference compensation circuit can have at least two operational modes of operation. In the first mode, the circuit can actively generate or output a compensation signal that cancels, corrects, or suppresses the interference. The second mode can be a standby, idle, power-saving, passive, or sleep mode.
