  • Patent number: 8711048
    Abstract: The invention provides a damage resistant antenna using a super-elastic flexible metallic material to form antenna radiating structures with a high damage threshold. The invention accounts for the electro-magnetic properties of the super-elastic flexible metallic material in the design of the shape and dimensions needed to form antenna radiating structures with consistent performance after repeated deploy, stow, and transport cycling of the antenna.

  • Patent number: 8342027
    Abstract: A method for determining a physical property of an object or fluid in a dynamic multi-path clutter environment comprises transmitting an RF interrogation signal to a wireless sensor physically coupled to the object or fluid (gas or liquid) in the dynamic multi-path clutter environment, wherein the wireless sensor is operable to receive the RF interrogation signal, produce a reference signal and a measurement signal, and retransmit the reference signal and the measurement signal in the dynamic multi-path clutter environment. The reference signal and measurement signal are delayed by the wireless sensor by an amount of time that may be a function of the unknown physical property. The method also comprises receiving the retransmitted reference signal and the retransmitted measurement signal and comparing them in the time domain in order to determine the unknown physical property of the object or fluid.

  • Patent number: 8009115
    Abstract: An antenna made up of small addressable conductive segments, or pixel elements, located in a dielectric space positioned over a two-dimensional pixel element actuator is presented. The small pixel elements can be actuated in less than a millisecond by the actuator to form patterns that create an array of patch antennas and associated transmission lines on the upper surface of the dielectric space. The pixel elements can be formed using small movable conductive particles such as metal flakes or metal chips.

  • Publication number: 20110001655
    Abstract: A method for determining a physical property of a structural member in a dynamic multi-path clutter environment is given. The method comprises transmitting an RF interrogation signal to a wireless sensor operable to receive the RF interrogation signal, produce a reference signal and a measurement signal, and transmit the reference signal and the measurement signal in the dynamic multi-path clutter environment. The reference signal is delayed by a first time delay and the measurement signal is delayed by a second time delay that is a function of the physical property to be determined. The first and second time delays are associated by a known relationship defined by the wireless sensor. The method further comprises receiving the transmitted reference signal and the transmitted measurement signal and comparing the transmitted reference signal and the transmitted measurement signal in the time domain. Finally, the method comprises using this comparison to determine the physical property of the structural member.

  • Patent number: 7576696
    Abstract: Antenna assemblies and corresponding modes of operation are provided where the first antenna assembly of the system is tuned to a first frequency band ?1 and the second antenna assembly of the antenna system is tuned to a second frequency band ?2. The ground plane of the first antenna assembly is configured as a frequency selective surface that is substantially reflective of radiation in the first frequency band and substantially transparent to radiation in the second frequency band. The second ground plane may also be configured as a frequency selective surface and may be reflective of radiation in the second frequency band. Any number of additional antenna arrays may be added so long as the outer arrays are transparent to the inner arrays.

  • Patent number: 7561109
    Abstract: An antenna made up of addressable conductive segments, or pixel elements, affixed to the top of each piston in a piston array is presented. The pixel elements can be activated in less than a millisecond to form an antenna array and transmission line pattern using movable pistons and a two-dimensional actuator. Each piston comprises a handle, a bottom conductive segment affixed to the top of the handle, a dielectric segment affixed to the uppermost surface of the bottom conductive segment, and a top conductive segment affixed to the uppermost surface of the dielectric segment. When the piston is not actuated, the top conductive segment forms part of a ground plane. The top conductive segment form part of the transmission line and antenna array patterns, the dielectric segment becomes a dielectric space and the bottom conductive segment forms part of the ground plane when the piston is actuated.
