  • Patent number: 10879582
    Abstract: A device and method of fabrication of a dielectrically reinforced formed metal antenna element enables an easily replaceable antenna element unlimited by PCB thickness constraints and planar structures. Modern fabrication methods are employed to embed pre-formed metal antenna structures in a rigid dielectric material. Conductive elastomer contacts provide electrical contact between an RF distribution PCB and the antenna element structures. A single layer of the dielectrically reinforced formed metal antenna elements may offer a simple yet effective antenna element capable of excellent RF connectivity up to 20 GHz. The individual elements are conformal to an installation, cooperative with additional elements, and easily replaceable with molded couplings attachable to the PCB with the flexible elastomers ensuring connectivity.

  • Patent number: 10824831
    Abstract: A method includes sending, by a reader, a radio frequency (RF) signal to a wireless sensor that includes an antenna having a tail section and a head section. The tail section is for placement in an RF limited area for sensing moisture in a first location of a vehicle under test and wherein the head section is for placement in a non-RF limited area. The method further includes receiving, by the reader, an RF response to the RF signal from the wireless sensor. The first RF response includes an indication of adjustment of one or more RF characteristics of the wireless sensor, which corresponds to a variance of the one or more RF characteristics from a desired value, which, in turn, corresponds to a level of moisture at the first location. The method further includes outputting, by the reader, a message regarding the level of moisture at the first location.

  • Patent number: 10805035
    Abstract: A secure wireless transceiver, such as a link 16 transceiver, receives signals using an antenna array having an SOC associated with each antenna element in the array. The SOC's digitize and channelize received data for transmission to a message nulling system that mitigates jamming. The antenna array can be conformal, and can replace an existing Link 16 blade. The disclosed transceiver can be a modified CMN-4 transceiver with digitizing and channelizing moved to the SoC's, and replaced by the nulling system. The transceiver uses applicable TRANSEC information to assign received data to the logical Link 16 channels before nulling, and embodiments apply nulling only to channels of interest, thereby improving the nulling and reducing side lobes. Embodiments distinguish between desired and unwanted signals based on known Link 16 signal features and/or situational awareness, rather than signal amplitudes, thereby enabling nulling of even weak jamming signals.
