  • Publication number: 20170324143
    Abstract: A connector assembly that provides a proper impedance connection between a CPW antenna mounted on automotive glass to a FAKRA-type connector. The connector assembly includes a PCB having a top surface and a bottom surface and being adhered to the glass. Vias are provided through the PCB to make electrical contact between metallization planes on the top surface and the bottom surface of the PCB. Terminals that are part of the connector extend through some of the vias, where ground terminals provide mechanical stability and make electrical contact with the metallization planes on the bottom surface of the PCB and a signal terminal provides an electrical connection to the antenna radiating element. The PCB is adhered to a substrate on which the antenna is mounted so that the metallization planes and microstrip lines make electrical contact with a CPW feed structure that feeds the antenna.

  • Publication number: 20170237148
    Abstract: An antenna assembly including a planar antenna formed on a dielectric substrate and a frequency selective impedance surface formed on the substrate and at least partially surrounding the antenna. The frequency selective impedance surface receives surface waves propagating along the dielectric substrate generated by the antenna, where the impedance surface mitigates negative effects of the surface waves by converting the surface wave energy into leaky-wave radiation, and also possibly providing some control of the radiation gain pattern of the antenna. In one embodiment, the dielectric substrate is vehicle glass, such as a vehicle windshield.

  • Patent number: 9536844
    Abstract: The disclosed antenna structures and electronic microsystems are capable of physically disappearing in a controlled, triggerable manner. Some variations provide an on-chip transient antenna comprising a semiconductor substrate containing ion-implanted hydrogen atoms and a conductor network comprising metals bridged by low-melting-temperature metals. Some variations provide an off-chip transient antenna comprising a flexible substrate containing a polymer, nanoporous silicon particles, and an oxidant for silicon, and a conductor network comprising metals bridged by low-melting-temperature metals. Other variations provide a method of introducing physical transience to a semiconductor integrated circuit, comprising thinning a substrate from the back side, implanting hydrogen ions into the thinned substrate to introduce latent structural flaws, depositing a semiconductor integrated circuit or sensor chip, and providing a controllable heating source capable of activating the latent structural flaws.

    Abstract: This invention is the Optically Powered and Controlled Non-Foster Circuit (OPCNFC) that is electrically floating; i.e., it does not have any metallic electrical/conductive connection to a power supply, ground, or control signal. Rather power and control signals are applied to the OPCNFC using optical energy. The Non-Foster Circuit (NFC) synthesizes negative inductance, negative capacitance, and/or negative resistance between metallic patches disposed in an array of an Artificial Impedance Surface (AIS).

  • Patent number: 9335568
    Abstract: An optical-waveguide grating modulator is compatible with high-frequency electrical modulation signals of limited bandwidth. The modulator comprises an optical grating formed in an optical waveguide constructed from electro-optic (EO) material and an electrode that is an RF waveguide or RF transmission line that conducts a traveling-wave electromagnetic (EM) field and that contains a portion of the optical-grating waveguide with a continuous grating. The RF input modulation signal is coupled into an RF EM field that propagates through the RF waveguide or transmission line in a direction that is parallel to the direction the light propagates in the optical-grating waveguide and that EM field overlaps the optical-grating waveguide. The light travels along the optical-grating waveguide preferably at the same velocity as the RF EM field travels along the RF waveguide or transmission line.
